patch to PD cpp

[Frank crash Edwards]

I have a single patch for the C preprocessor which was posted to mod.sources
many moons ago.  A local archiver had it available when I needed it, and in
using it I received "end-of-input" messages where I shouldn't have.

It turns out, after much debugging time, that the token parser *WILL*
recognize an opening comment token ("/*") if it is contained within
double quotes!!  In the NetHack2.2 source, are subroutine calls which
contain this particular sequence (do_name.c, for one).

The following two lines will check for the '/*' combination in the
skip_until_newline routine.  It probably shouldn't be done there, but
you know how these quick little fixes get ;-).

File:  cpp6.c, routine skipnl()
132a133,134
> 	    if (c == '\\') get();
> 	    else if (c == '"') instring = !instring;
