This reverts commit 3ec807e99a.
Our nightly build test cases rely on the PRN sequence generated by GNU
libc's random(). We used to have such a PRNG in our tree (derived
from an old version of GNU libc's), for use under Windows. Thus we
got the same PRN sequence on both our nightly test systems. Commit
3ec807e9 switched to -liberty under Windows and removed our random().
Now we got a different sequence there, breaking the test cases.
Test cases still don't work on non-Windows systems where random()
doesn't match GNU libc's. We should switch to a PRNG that produces
the same sequence everywhere.
Conflicts:
src/lib/w32/w32misc.h
POSIX equivalents instead of using the WIN32 rand/srand functions.
The files were derived from GNU libc source.
(empth_threadMain) [_WIN32]: Remove the srandom() as the
POSIX equivalent are not thread specific as the WIN32 functions were.
