# Enable distcheck warnings and Werror only for gcc versions that support them,

# and only after we've run the configure tests.

# Some configure tests fail (like checking for cos in -lm) if we enable these

# Werror flags for configure too (for example -Wstrict-prototypes makes

# configure think that -lm doesn't have cos, hence its in libc).
