Gawk has been compiled and tested under OS/2, DOS, and Win32 using

the GNU development tools from DJ Delorie (DJGPP; DOS with special

support for long filenames under Win95), Eberhard Mattes (EMX; OS/2,

DOS, and Win32 with rsxnt), and Jan-Jaap van der Heijden (Mingw32;

Win32). Microsoft Visual C/C++ can be used to build a Win32 version for

Windows 9x/NT, and MSC can be used to build 16-bit versions for DOS and

2. The following table illustrates some of the differences among the various
115
116
compiled versions of gawk. For example, the djgpp version runs on all the
116
117
systems, but with differing capabilities: it supports long filenames under
117
Win-95 but not under NT, and it runs as a DPMI application under OS/2 (which

Users interested in Win32 applications may also wish to examine the
175
Cygnus GNU-Win32 Project at http://www.cygnus.com, or the Mingw32 work
176
at http://agnes.dida.physik.uni-essen.de/~janjaap/. Win32 gawk will
177
often require that utilities run from within gawk be Win32 (e.g., the
178
tests place this requirement on the cat utility).

Spencer's "awf". Use GNU C versions if possible.

4. builtin.c of gawk-3.0.[1-6] triggers a bug in MSC 6.00A. The makefile

works around the bug by compiling builtin.c without optimizations (-Od).

In limited testing, it appears that inserting some dummy code in

builtin.c can provide a better solution than disabling optimizations.
