You need to make a couple of minor changes.

In f2c/libf77/s_paus.c, change the definition of pause as
follows:

	...
	extern int getpid(void), isatty(int);
	#ifndef __GO32__
	extern int pause(void);
	#endif
	...

In f2c/libi77/rawio.h, add the following three lines to the beginning
of the file:

	#ifdef __GO32__
	#undef MSDOS
	#endif
	...

Then change the declarations of read and write as follows:

	...
	extern int close(int);
	#ifndef __GO32__
	extern int read(int,void*,size_t), write(int,void*,size_t);
	#endif
	...

I use ndmake, so the makefiles must be modified to handle the
character limit on the command line under MS-DOS.  I've also
chosen to make one library, libf2c.a.  I execute then with

	cd libf77
	ndmake -f makefile.djg
	cd ..\libi77
	ndmake -f makefile.djg

Copies of these makefiles are tacked onto the end.  I've also tacked
on my makefile for f2c/src.  You need bison for the way its currently
set up.  You may have to fiddle a bit if xsum gives you problems.
Also, make sure the CFLAGS option -m486 is appropriate for your
machine.
