Re: [Maxima-discuss] Compiling pregexp.lisp fails with GCL?

[Camm Maguire]

Greetings!  OK, I think I've gotten to the bottom of the inline
semantics issue.

The original conditional was correct -- gcc-4 was the last version with
the old semantics.  Unfortunately, autoconf has since automatically
added -std=gnu11 to probed $CC variables, taking gcc-4 to the new
semantics.  We probe the semantics directly now.  Tested in current
debian unstable, and debian jessie with and without -std=gnu11, and
seems to work.  Please try current Version_2_6_13pre (tag
Version_2_6_13pre120) and let me know if it works for you too!

Take care,
