Configuring text/groff on Solaris 10 using lang/gcc34 fails:

checking that header files support C++... no
configure: error: header files do not support C++
                   (if you are using a version of gcc/g++ earlier than 2.5,

for C++

In file included from /usr/include/stdio.h:22,
                 from conftest.cpp:11:
/usr/include/sys/feature_tests.h:336:2: #error "Compiler or options invalid; 
UNIX 03 and POSIX.1-2001 applications      require
the use of c99"

Removing the recently added CFLAGS options for SunOS from Makefile lets this

committer introduces...
>How-To-Repeat:

>Fix:
Use the CFLAGS only on Solaris 11 or with GCC 4.
