Fork over build.log too if you aren't already working on it? Thank you for the report!
(Just as a note: this package is somewhat "special", so I wouldn't be surprised if -O0 -ggdb is part of the problem. Attempting with vanilla CFLAGS="-O2" would help.)
Created attachment 659432 [details] The complete build log
Using CFLAGS="-O2" compiles with no error.
No idea if it helps, but the latest upstream commit touches this file: https://github.com/libtom/tomsfastmath/commit/55863ae1d
Could you report this upstream? They are kind of open to different configurations IIRC. Patching this package isn't a great idea if we can help it.
