Re: [Bug-gnubg] bad __attribute__ handling breaks w/newer standards, newer gcc, & glibc and causes infinite loop - FIX NEEDS TESTING

[Michael Petch]

I have put away a fix for this issue and did some other cleanup that
involved files that may be using __attribute__. I took the approach of
moving the __attribute__ check to configure.ac using
ax_c___attribute__.m4 . common.h now includes config.h .
This fix could use some testing, so please let me know if i have caused
any regressions or something isn't fixed.

The Changelog is here:

    Mike Frysinger where __attribute__ and  _GNU_SOURCE may not
    be properly defined in some situations. This may result in
    an infinite loop on newer compilers.
