Subject: Re: issues with headers?
there was an devel-m4.diff patch available from gregorr website where the
gcc musl patch can be found albiet the m4 was in a different directory and
didn't work.
https://github.com/GregorR/musl-pkgsrc-patches/blob/master/devel-m4.diff
I attached the config.log from the gmp folder. It complains when trying to
run -std=c99 or -std=gnu99 -E
