#--------------------------------------------------------------------
#	The code below deals with several issues related to gettimeofday:
#	1. Some systems don't provide a gettimeofday function at all
#	   (set NO_GETTOD if this is the case).
#	2. SGI systems don't use the BSD form of the gettimeofday function,
#	   but they have a BSDgettimeofday function that can be used instead.
#	3. See if gettimeofday is declared in the <sys/time.h> header file.
#	   if not, set the GETTOD_NOT_DECLARED flag so that tclPort.h can
#	   declare it.

#	The code below deals with several issues related to gettimeofday:
#	1. Some systems don't provide a gettimeofday function at all
#	   (set NO_GETTOD if this is the case).
#	2. SGI systems don't use the BSD form of the gettimeofday function,
#	   but they have a BSDgettimeofday function that can be used instead.
#	3. See if gettimeofday is declared in the <sys/time.h> header file.
#	   if not, set the GETTOD_NOT_DECLARED flag so that tclPort.h can
#	   declare it.
