I was also compiling with gimp with gcc-7 successfully before my couple of
catastrophes, so I don't know why it would start to fail with the new os.

I was confused because I read something about compiler problems on
this list, but I wasn't having them.

==multiple compilers installed==
My software installer just announces that it is updating what it considers
to be "gcc", copies that binary into the directory of its choice and simply
ignores the previous gcc.  Compiler cruft!  When today started I had
gcc-4 from the installer and gcc-7 which I installed with the "real"
software.
I was thinking about getting gcc-5 just so I would have a complete set.

I am pretty sure that each new number of compiler is a new version,
hence the number.

I don't think I am the only person who has more than one version of gcc.
