can't compile Python modules that use C99

[Zooko Wilcox-O'Hearn]

Using Python 2.5.2-0nexenta2 . When I try to build a Python module that is written in C99 I get this failure:

gcc -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -g -O2 -O2 -fPIC -I/usr/include/python2.5 -c zfec/_fecmodule.c -o build/temp.solaris-2.11-i86pc-2.5/zfec/_fecmodule.o -std=c99

/usr/include/sys/feature_tests.h:353:2: error: #error "Compiler or options invalid for pre-UNIX 03 X/Open applications and pre-2001 POSIX applications"

I believe that this is caused by this issue in Python:

http://bugs.python.org/issue1759169

There is a patch (by me) on that ticket. Here is the patch:

Please apply that patch to the Nexenta packaging of Python.
