Subject: Now that this file is no longer used by any libc C file, get rid of checks
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=248a8d5abba8744efc88ac5094b22357ab8f62e4;p=openbsd

Now that this file is no longer used by any libc C file, get rid of checks
for the _LIBC preprocessor symbol.

Also move the CC64FSZ and BIAS defines earlier in order to only have one
!_LOCORE block.
