What gcc6 issues did you have? I fixed some for FreeBSD, maybe it

Alright, here's the deal. GCC>4 turns on C11 mode by default. It's a
standards error to compile an XPG5 (or older) application with a C99 or
newer compiler. Sun systems actually call you on this.
The answer is -ansi (or -std=c89, -std=c90, etc), and it fixes that
particular problem. However, more surface.
When you get a chance, can you tell me if you get a clean build with
-ansi on a GCC6 system? I'll go from there.
Ah yes. I created a branch to test -std=gnu99/std99 C support a few
weeks ago, and saw these issues too. I was able to build with gnu99
(otherwise with std99, certain localization functions we need were not
available). I figured we'd punt till the next release after this one.
In master, on linux/bsd we use -ansi (C89), and this works, even with
gcc6. I'd like to move to at least C99 someday, since it lends itself
to better C code, but was going to save that for after an official
release. C99 also complains about a lot more stuff, so many more
warnings :)
So, if you are using gcc, use -ansi, at least until we take the plunge.
