[Groff] Compiling groff 1.18.2 with gcc3 under Cygwin

[Alejandro Lopez-Valencia]

I think I have tracked down failure to compilegroff with gcc 3.x to a 
problem with the supplied GNU getopt header. The folowing patch works:

$ diff -u groff/src/include/getopt.h groff_build/src/include/getopt.h

 /* Many other libraries have conflicting prototypes for getopt, with
    differences in the consts, in stdlib.h.  To avoid compilation
    errors, only prototype getopt for the GNU C library.  */

That is, gcc3 needs this prototype declared:

extern int getopt (int ___argc, char *const *___argv, const char *__shortopts)

Notice that the Mingw32 build fails due to other problems with differences 
in the mingw prototypes for mktemp and related functions:

g++ -mno-cygwin -mconsole -I. -I/home/alv/groff/src/libs/libgroff 
-I/home/alv/gr
off_w32/src/include -I/home/alv/groff/src/include -DHAVE_CONFIG_H -g 
-O2  -c /ho
me/alv/groff/src/libs/libgroff/tmpname.cc
/usr/include/mingw/io.h: In function `int gen_tempname(char*, int)':
/usr/include/mingw/io.h:145: too many arguments to function `int mkdir(const
   char*)'
/home/alv/groff/src/libs/libgroff/tmpname.cc:105: at this point in file
make[2]: *** [tmpname.o] Error 1

make[1]: *** [src/libs/libgroff] Error 2
make[1]: Leaving directory `/home/alv/groff_w32'
make: *** [all] Error 2

I guess that might be a bug in mingw's headers and needs to be reported 
elsewhere.

Can anyone test if forcing the declaration of the getopt prototype makes 
possible compiling groff in MacOSX with gcc3 (You may need to update your 
gcc3 to version 3.2.1, I am using cygwin binaries based on a CVS snapshot 
one or two weeks before gold release)?
