To install EMX 0.9d (a 32-bit DOS-extended C compiler)
do the following (assuming you are installing on the C 
drive, and you have DOS installed):

Obtain README.DOC, INSTALL.DOC, EMXRT.ZIP, EMXDEV1.ZIP,
EMXDEV2.ZIP, GNUDEV1.ZIP, GNUDEV2.ZIP, GPPDEV1.ZIP,
GPPDEV2.ZIP EMXFIX04.ZIP from:

http://hobbes.nmsu.edu/cgi-bin/h-browse?sh=1&dir=//pub/os2/dev/emx/v0.9d

You then simply go to c:\ and unzip (not pkunzip) the above
archives.  EMXFIX04.ZIP should be the last one unzipped.

Then you add the following three statements to your autoexec.bat:

set C_INCLUDE_PATH=c:/emx/include
set LIBRARY_PATH=c:/emx/lib
set CPLUS_INCLUDE_PATH=c:/emx/include/cpp;c:/emx/include

Then you add c:\emx\bin to your PATH.

Then you reboot your machine.

Then you compile your C program called world.c by going
gcc world.c

Then you compile your C++ program called world.cpp by going
gcc world.cpp -lstdcpp

And that's it!  GNU/EMX takes up 16.5 meg of disk space.

Note that there is a name clash with the cpp.exe from
Turbo C++ 1.01, so ensure that EMX is higher up in the path
than TC\BIN if you have it installed.
