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).

PATH_MAX]: Don't assume that the user's buffer is any longer than the amount necessary to hold the filename; the Hurd getcwd uses the *entire* contents of the buffer, however long it is specified to be. * posix/getconf.c: De-ANSI-fy. Recognize POSIX.2 constant names. since these do not depend on the platform.
