Yes, I have ported the cdecl utility (it translates between c
declaration syntax and English) to MS-DOS from UNIX by doing exactly
what you are asking about!  I ran the lex and yacc portions of the
make procedure under UNIX, and then compiled the resulting C code,
along with the rest of cdecl, using the Microsoft C (rel 4.0) under
MS-DOS 3.2.  The result is that the utility runs under MS-DOS as it
does under UNIX.  I'm now hacking up the lex and yacc sources to
understand the far and near extensions, so that it will be more
useful to MS-C developers.

The development system here is ideal for the task: an AT&T
PC6300PLUS running Simul-Task.  It allows me to run MS-DOS
applications from within UNIX programs.  What I use to make
cdecl.exe is a single UNIX Makefile that runs lex and yacc as usual,
and then runs cl as a dos command!  The same makefile can be used to
make cdecl (the unix executable) and cdecl.exe.  It invokes cc to
make the unix flavor, and cl to make the dos flavor.
