It is close though on Solaris < 10 it looks like this in <sys/types.h>:
#if defined(__EXTENSIONS__) || \
        (!defined(_POSIX_C_SOURCE) && !defined(_XOPEN_SOURCE))


Unfortunately this patch causes a different problem.
While it actually allowed dtotimespec.c to build on Solaris 2.6 most 
everything else now fails with this error:

depbase=`echo accept4.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\

The same happens on Solaris 7 and 9 (8 not tested).

The problem now is that struct fd_set is not defined since gnulib 
<sys/select.h> is parsed before system <sys/select.h>.
