#
# -D flags:
#
# -D__GL__ - if your system supports gl graphics library (SGI 4d & IBM R6000).
#
# -D__X11__ - if your system supports X11. Only one of __GL__ or __X11__ should
#	be used.
#
#  Emulation to the following function are available by defining the
#  following. Look at misc_lib/xgeneral.c/h for implementation.
# -DGETCWD - if getcwd is not defined in this system.
# -DSTRSTR - if strstr is not defined in this system.
# -DSTRDUP - if strdup is not defined in this system.
# -DSTRICMP - if stricmp and strincmp are not defined in this system.
#
# -DTIMES - if times is defined in your system, otherwise uses time.
#
# -DRAND - if the (s)rand random number generator exists.
# -DRAND48 - ?rand48 random number generators exists.
#	If non of RAND or RAND48 are defined, (s)random is used.
#
# -DUSLEEP - if usleep is defined in the system.
# -DSGINAP - on sgi systems instead of usleep.
#
# -DNO_VOID_PTR - if your C compiler does not support (void *).
#
# -DUSE_VARARGS - if your system does not have stdarg.h and have the old
#	varargs.h.
#
# -DNO_CONCAT_STR - if 'char *p = "This is" "one string";' is illegal.
#
# -DGRAPDRVS - any combination of of 'xgldrvs', 'xgladap', 'x11drvs'.
#
# Other, possibly useful defines (for c code development):
#
# -DDEBUG - for some debugging functions in the code (that can be invoked
#		from a debugger).
