Subject: legacy junk compatibility grab-bag
X-Git-Tag: v0.8.9~4
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=ba6a9e7734aaff8f4e7d49b888f9dd1954bc92b1;p=oweals%2Fmusl.git

legacy junk compatibility grab-bag

- add the rest of the junk traditionally in sys/param.h
- add prototypes for some nonstandard functions
- add _GNU_SOURCE to their source files so the compiler can check proto
