Implementation of sigwait function from POSIX.1c. * sysdeps/stub/sigwait.c: New file. Stub version of sigwait. Wed Oct 30 02:01:17 1996 Richard Henderson <rth@tamu.edu> * sunrpc/xdr_float.c (xdr_float): Handle sizeof(float)!=sizeof(long), but don't bother going farther than sizeof(float)==sizeof(int). (xdr_double): Handle little-endian machines! Handle sizeof(double) != 2*sizeof(long), though again don't bother with more than int.
