Subject: fix mrand48/jrand48 return value on 64-bit archs
X-Git-Tag: v1.1.16~11
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=adfe682eb0d77c6afc751f5e407d9da39623c24e;p=oweals%2Fmusl.git

fix mrand48/jrand48 return value on 64-bit archs

POSIX specifies the result to have signed 32-bit range. on 32-bit
archs, the implicit conversion to long achieved the desired range
already, but when long is 64-bit, a cast is needed.
