Check for stdint.h in C++, not in C.

* aclocal.m4 (GROFF_STDINT_H): New function,
* configure.ac: Check for stdint.h with GROFF_STDINT_H instead of
AC_CHECK_HEADERS.
* configure, src/include/config.hin: Regenerated.
* src/libs/libgroff/tmpname.cc: Use HAVE_CC_STDINT_H.


* src/libs/libgroff/maxfilename.cc:
s/HAVE_LIMITS_H/HAVE_CC_LIMITS_H/.

* src/roff/troff/node.cc (unbreakable_space_node::tprint): Don't
emit word marker.
