# Setting these makes sure that the subsequent include files know that
# we are going to be threaded so they should do whatever they need to
# support this. In particular, this makes the global variable 'errno'
# become thread safe by replacing it with a call to the internal function
# ___errno() on Solaris - and should do something similar on other operating
# systems. Solaris also supports _TS_ERRNO to enable thread-safe errno
# _REENTRANT is also required for the tempnam() function to be properly
# thread-safe.
