Notes:
(1) Two makefiles for djgpp/GNU make are provided, one for djgpp 1.12 and one
for djgpp v2.x. In addition, the Unix makefile (unix/Makefile) contains
a djgpp v2.x target using the go32-gcc cross compiler on Linux. Read the
appropriate makefile sections for details.
(2) The makefile for emx+gcc has been used with GNU Make ports from DJGPP and
the GNUish MS-DOS project. Other make utilities may work, too. The
resulting executables require emx.exe or rsx.exe to run (akin to djgpp
1.x's go32.exe).
(3) The OS/2 makefile includes several (cross compilation ?) targets to
generate MS-DOS executables which can be used with MSC 6.0 or later
(`mscdos', 16-bit), Watcom C/C++ 9.0 or later (`watcom16dos', 16-bit;
`watcomdos' and `pmodew', 32-bit) and emx+gcc 0.9c or later (`gccdos',
32-bit). These targets have only been tested in cross-compilation from
OS/2 to MS-DOS, but they may work on a plain MS-DOS system, when a proper
make utility is available.
