groff 1.20 on Interix (all_source)

/dev/fs/C/src/groff-1.20/src/libs/libgroff/hypot.cpp: In function `double
   groff_hypot(double, double)':
/dev/fs/C/src/groff-1.20/src/libs/libgroff/hypot.cpp:33: error: `isnan'
   undeclared (first use this function)
/dev/fs/C/src/groff-1.20/src/libs/libgroff/hypot.cpp:33: error: (Each
   undeclared identifier is reported only once for each function it appears
   in.)
/dev/fs/C/src/groff-1.20/src/libs/libgroff/relocate.cpp: In function `char*
   searchpath(const char*, const char*)':
/dev/fs/C/src/groff-1.20/src/libs/libgroff/relocate.cpp:88: error: `realpath'
   undeclared (first use this function)
/dev/fs/C/src/groff-1.20/src/libs/libgroff/relocate.cpp:88: error: (Each
   undeclared identifier is reported only once for each function it appears
   in.)
 

similar for fdopen in a few places (tmpfile.cpp, maybe index.cpp)
 

It would be nice to just:
 

#if defined(__INTERIX) && !defined(_ALL_SOURCE)
#define _ALL_SOURCE
#endif
 

in lib.h, but that invites clashing declarations like:
 

/src/groff-1.20/src/include/lib.h:120: error: declaration of C function `int
   strncasecmp(const char*, const char*, int)' conflicts with
/usr/include/strings.h:68: error: previous declaration `int strncasecmp(const
   char*, const char*, unsigned int)' here

 
and similar for putenv.
 

So this form limits the impact.
 

I had to use configure -without-x, and got errors building the documentation, 
ok,
I might look into those later.
