gentoo/dev-libs/libdnsres/files/libdnsres-0.1a-C99.patch
NHOrus 23f0219c99 dev-libs/libdnsres: Port to C99, musl 
Inlude some musl libraries for transient dependency fix.
Port a function from glibc as a replacement for missing on musl.
Fixed some of the badness hidden in autotools, legacy types.
Fold seds.
