Build fails with LLVM flang 19

[awvwgk]

Looks like flang cannot compile fpm 0.10.1 at the moment. The build of the bootstrapper fails with multiple errors.

See conda-forge/fpm-feedstock#27

Error message from building the bootstrapper, unfortunately not mapped to the fpm source files:

flang compilation was fixed in #1011 #1013 #1024 #1028 #1029, trunk builds just fine so I will close this one. For the package managers, a new release may be needed.
