Then I cannot understand why it is complaining here! Do you get the same
error when you manually run this:

$ /gnu/store/whkq7f2d702hqnrdd2cqskqxdx267283-profile/bin/bash -O
extglob -n ./scripts/libmakepkg/executable/checksum.sh

Yeah... but the problem here is that you're generating pedantic warnings
for lacking ISO C conformance in your libc headers, which is just plain
useless. Might as well disable all warnings.

If you only build lib/libalpm/ and src/pacman/ then sure. Do you need a
working makepkg too, though?
