- MSDOS mode for launching programs (via a batch file). The
- MSDOS mode style execution has not been tested that carefully

(Consensys). Also MinGW includes sh (http://mingw.org/).
GNU make and brain-dead shells (BATCH_MODE_ONLY_SHELL):
- Some versions of Bourne shell do not behave well when invoked
- as 'sh -c' from CreateProcess(). The main problem is they seem
- to have a hard time handling quoted strings correctly. This can
- be circumvented by writing commands to be executed to a batch
- file and then executing the command by calling 'sh file'.
-
- To work around this difficulty, this version of make supports
- a batch mode. When BATCH_MODE_ONLY_SHELL is defined at compile
- time, make forces all command lines to be executed via script
- files instead of by command line. In this mode you must have a
- working sh.exe in order to use parallel builds (-j).
-
- A native Windows32 system with no Bourne shell will also run
- in batch mode. All command lines will be put into batch files
- and executed via $(COMSPEC) (%COMSPEC%). However, parallel
- builds ARE supported with Windows shells (cmd.exe and
- command.com). See the next section about some peculiarities
- of parallel builds on Windows.

Support for parallel builds
- Parallel builds (-jN) are supported in this port, with 1
- limitation: The number of concurrent processes has a hard
- limit of 64, due to the way this port implements waiting for
- its subprocesses.

GNU make and Cygnus GNU Windows32 tools:
- Good news! Make now has native support for Cygwin sh. To enable,
- define the HAVE_CYGWIN_SHELL in config.h and rebuild make
- from scratch. This version of make tested with B20.1 of Cygwin.
- Do not define BATCH_MODE_ONLY_SHELL if you use HAVE_CYGWIN_SHELL.

GNU make handling of drive letters in pathnames (PATH, vpath, VPATH):
- There is a caveat that should be noted with respect to handling
- single character pathnames on Windows systems. When colon is
- used in PATH variables, make tries to be smart about knowing when
- you are using colon as a separator versus colon as a drive
- letter. Unfortunately, something as simple as the string 'x:/'
- could be interpreted 2 ways: (x and /) or (x:/).
-
- Make chooses to interpret a letter plus colon (e.g. x:/) as a
- drive letter pathname. If it is necessary to use single
- character directories in paths (VPATH, vpath, Path, PATH), the
- user must do one of two things:
-
- a. Use semicolon as the separator to disambiguate colon. For
- example use 'x;/' if you want to say 'x' and '/' are
- separate components.
-
- b. Qualify the directory name so that there is more than
- one character in the path(s) used. For example, none
- of these settings are ambiguous:
-
- ./x:./y
- /some/path/x:/some/path/y
- x:/some/path/x:x:/some/path/y
-
- Please note that you are free to mix colon and semi-colon in the
- specification of paths. Make is able to figure out the intended
- result and convert the paths internally to the format needed
- when interacting with the operating system, providing the path
- is not within quotes, e.g. "x:/test/test.c".
-
- You are encouraged to use colon as the separator character.
- This should ease the pain of deciding how to handle various path
- problems which exist between platforms. If colon is used on
- both Unix and Windows systems, then no ifdef'ing will be
- necessary in the makefile source.

GNU make test suite:
- I verified all functionality with a slightly modified version
- of make-test-%VERSION% (modifications to get test suite to run
- on Windows NT). All tests pass in an environment that includes
- sh.exe. Tests were performed on both Windows NT and Windows 95.

Pathnames and white space:
- Unlike Unix, Windows 95/NT systems encourage pathnames which
- contain white space (e.g. C:\Program Files\). These sorts of
- pathnames are valid on Unix too, but are never encouraged.
- There is at least one place in make (VPATH/vpath handling) where
- paths containing white space will simply not work. There may be
- others too. I chose to not try and port make in such a way so
- that these sorts of paths could be handled. I offer these
- suggestions as workarounds:

- 1. Use 8.3 notation. i.e. "x:/long~1/", which is actually

- 2. Rename the directory so it does not contain white space.

- If you are unhappy with this choice, this is free software
- and you are free to take a crack at making this work. The code
- in w32/pathstuff.c and vpath.c would be the places to start.

Pathnames and Case insensitivity:
- Unlike Unix, Windows 95/NT systems are case insensitive but case
- preserving. For example if you tell the file system to create a
- file named "Target", it will preserve the case. Subsequent access to
- the file with other case permutations will succeed (i.e. opening a
- file named "target" or "TARGET" will open the file "Target").

+ file named "target" or "TARGET" will open the file "Target").
- By default, GNU make retains its case sensitivity when comparing
- target names and existing files or directories. It can be
- configured, however, into a case preserving and case insensitive
- mode by adding a define for HAVE_CASE_INSENSITIVE_FS to
- config.h.W32.

- For example, the following makefile will create a file named
- Target in the directory subdir which will subsequently be used
- to satisfy the dependency of SUBDIR/DepTarget on SubDir/TARGET.
- Without HAVE_CASE_INSENSITIVE_FS configured, the dependency link
- will not be made:

- touch $@
+ subdir/Target:
+ touch $@
- SUBDIR/DepTarget: SubDir/TARGET
- cp $^ $@
+ SUBDIR/DepTarget: SubDir/TARGET
+ cp $^ $@
- Reliance on this behavior also eliminates the ability of GNU make
- to use case in comparison of matching rules. For example, it is
- not possible to set up a C++ rule using %.C that is different
- than a C rule using %.c. GNU make will consider these to be the
- same rule and will issue a warning.

SAMBA/NTFS/VFAT:
- I have not had any success building the debug version of this
- package using SAMBA as my file server. The reason seems to be
- related to the way VC++ 4.0 changes the case name of the pdb
- filename it is passed on the command line. It seems to change
- the name always to to lower case. I contend that the VC++
- compiler should not change the casename of files that are passed
- as arguments on the command line. I don't think this was a
- problem in MSVC 2.x, but I know it is a problem in MSVC 4.x.
