[issue2552] test_ctypes failed Python 2.6a2 Solaris 10 SUN C

So the proper fix for that would be to port it to SunPro, of course.

I'm not sure whether that would be much better than the status quo,
though. People would continue to complain that the ctypes module is not
built.

Why do you consider the current behaviour incorrect?

There are several ways. One is to skip compilation in setup.py, for
which you should then determine whether the compiler is gcc. For
that, you could look at ac_compiler_gnu in configure.in, and
set a variable in Makefile.pre.in if the compiler is GCC. Then,
in setup.py, you could look for that variable as parsed from
the Makefile, and skip _ctypes accordingly.

Alternatively, you could check for __GNUC__ when compiling
ctypes, and make the compiler produce a better-understandable
#error.

Martin
