This version of GNU make has been tested on Microsoft Windows 2000/XP/2003.
It has also been used on Windows 95/98/NT, and on OS/2.
It builds natively with MSVC 2.x, 4.x, 5.x, 6.x, and 2003 as well as
.NET 7.x and .NET 2003.
It builds with the MinGW port of GCC (tested with GCC 3.4.2).

The Windows 32-bit port of GNU make is maintained jointly by various
people. It was originally made by Rob Tulloh.

GNU make and sh.exe:

builds ARE supported with Windows shells (cmd.exe and

of parallel builds on Windows.
Support for parallel builds
Parallel builds (-jN) are supported in this port, with 2
limitations:
- The number of concurrent processes has a hard limit of 64,
due to the way this port implements waiting for its
subprocesses;
- The job server method (available when Make runs on Posix
platforms) is not supported, which means you must pass an
explicit -jN switch to sub-Make's in a recursive Makefile.
If a sub-Make does not receive an explicit -jN switch, it
will default to -j1, i.e. no parallelism in sub-Make's.

Building GNU make on Windows NT and Windows 95/98 with Microsoft Visual C:
I did not provide a Visual C project file with this port as
the project file would not be considered freely distributable
(or so I think). It is easy enough to create one, though, if
you know how to use Visual C.
I build the program statically to avoid problems locating DLL's
on machines that may not have MSVC runtime installed. If you
prefer, you can change make to build with shared libraries by
changing /MT to /MD in the NMakefile (or in build_w32.bat).
The program has not been built for non-Intel architectures (yet).
I have not tried to build with any other compilers than MSVC. I
have heard that this is possible though so don't be afraid to
notify me of your successes!
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 legal under Unix too, but are never encouraged.
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
