problem with anything to do with gnulib on Solaris UNIX

[Dennis Clarke]

Good day gnulib and or diffutils folks :

Minor issue on ye old sparcv9 Solaris 10 where the compile of diffutils
goes perfect in strict C99 mode. The testsuite fails when it tries to go
after the gnulib-tests and that stops the show.

     So I ripped out the gnulib-tests from the Makefile.foo and that
seems to solve everything just fine :

pollux$ pwd
/usr/local/build/diffutils-3.9_SunOS5.10_sun4u.003
pollux$
pollux$ uname -a
SunOS pollux 5.10 Generic_150400-67 sun4u sparc SUNW,UltraAX-i2
pollux$

I had already built all this before so :

pollux$ diff --version

Problem solved on Solaris and maybe we can detect __SunOS or something
to get past that?

Most GNU programs are not plain ISO C applications, but rather POSIX
applications. For instance, many GNU source packages have a
  #include <unistd.h>
here or there. Since <unistd.h> is not specified by ISO C [1], but by
POSIX [2], it makes no sense to attempt to build such programs in strict
C99 mode.

In particular, GNU diff opens its files through open(), not fopen(), and
is thus not an ISO C application.

Your build thus could already have failed way earlier than in the gnulib-tests.
