>Description:
Some python extensions don't build on x86 solaris 10 with gcc 4.4.3. They fail 
with these error:

     and pre-2001 POSIX applications"
*** Error code 1

The problem seems that "include/python2.6/pyconfig.h" defines  
"_XOPEN_SOURCE=500", which clashes with "_STDC_C99" and not "_XPG6"

I noticed this in these packages:
graphics/py-cairo
net/py-ORBit
sysutils/py-dbus
>How-To-Repeat:

>Fix:
A workaround is to put "CFLAGS.SunOS+= -D_XPG6" in the Makefiles.
