# If you need a special kind of assembler (eg. as), set $AS. If $AS is not
# set, $CC is used.
# Special flags for $AS are taken from $COMMON_AFLAGS, if it exists or
# from $COMMON_CFLAGS otherwise.
# If X11 is installed in a directory of it's own, you can specify that
# directory in $X11BASEDIR. $X11LIBDIR will then point to $X11BASEDIR/lib
# and $X11LDFLAGS will contain -L$X11LIBDIR. The same applies to $X11INCDIR.
# If only one part is in a nonstandard place (eg. the libs), you
# can set one of the $X11LIBDIR/X11INCDIRs, too.
