you should provide the OS gcc version etc...

This happens at least on macOS Sonoma (14.x) with Xcode 15.

Seems to be a GCC extension to allow this.

I have also encountered this problem recently. Is there any way to solve it?

I went back to a really old version from 2016 or so that I had used before and which worked well for my simple needs. Back then it still compiled ok on other compilers.

The commit in question is 5394b2c. It replaced literals by expressions for initialization of some values. Gcc includes builtin functions for pow10f and the like, but Clang does not—unfortunately.

Could you rename the issue to »Fails to build with CLang«?

Maybe it's possible to move all these initialization values to a file that can be generated with a little tool. Possibly with a configure option --with-rebuild-init-values. But this file should be fixed and included in git.
