Whether _POSIX_SOURCE has to be used or not is tested with the
availability of the function `fileno'.  (Please check the config.log
file whether _POSIX_SOURCE is really not set on your platform.)
Apparently this isn't enough, so will add fdclose to the GROFF_POSIX
m4 macro.  Since fdopen is a POSIX.1 function this should be
sufficient, and _POSIX_C_SOURCE isn't needed.  Please correct me if
I'm wrong -- Interix 3.5 has then to be handled specially since it is
not conformant to POSIX.1.

The fix (see below) should also correct the problem with strncasecmp
automatically since the autoconf tests for function declarations
include the definitions of all the AC_DEFINES performed so far.

I don't know the reason for this failure.  Maybe it is a compiler
problem since you are the first who is reporting this.  Have you tried
compiling groff without optimization?  Can you try a different g++
version?
