The error can be worked around with -std=c++17

This is due to a collision with the I macro used by gnu's complex.h

Thank you.

I believe there are other headers that have this issue, such as fmt/ranges.h. Would you like me to raise another issue/enumerate them?

Sorry for the slow reply.

I repeated the original reproducer with all headers found in include/fmt. The only errors I see are with

ranges.h
std.h

I wasn't able to test with locale.h, that header didn't seem to exist on godbolt.
