Greetings!  Yes this is what I've done in the test version of maxima in
debian sid too.

gcc-5 broke the old gcl inline semantics, provoking a significant
change.  I tried to make the gcl code backward compatible, but haven't
tested this extensively.  If you have examples of non-compatibility,
please forward them to me.  Again, I take from the above you are
referring to the 2.6.13pre source packaged in debian sid as 2.6.12-21.
2.6.12 (packaged in debian stable as 2.6.12-1) should compile fine with
old gcc, and not with gcc-5.

Good to see gcl is useful at least to some.

Take care,
