Subject: make real symbols for the legacy (nonstandardized) utmp functions
X-Git-Tag: v0.7.0~78
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=eee150f39c294883841d4f3ad9ce290ea1529a9e;p=oweals%2Fmusl.git

make real symbols for the legacy (nonstandardized) utmp functions

this is needed in the long term for ABI compatibility anyway, and in
the immediate, it helps with building broken programs like GNU screen
that try to prototype the functions themselves rather than using the
header.
