# Since musl doesn't provide error.h we need to check before adding it. If
# error.h is present in system only then we include it else we use err.h.
# Already there exists a bug report for this upstream [1]. The devs are open to
# a custom implementation of error but for now this patch for do it.
#
# [1]: https://github.com/libratbag/libratbag/issues/1253

# Closes: https://bugs.gentoo.org/830557
