>Description:
	Working on with libjpeg I found that FreeBSD port does not provide
	any usage of --enable-maxmem configure option. The proposed patch
	solves this issue.
	
>How-To-Repeat:
	Try to make libjpeg from ports with maxmem limit. You won't be able
	to do this without digging into Makefile.
	
>Fix:

	
	Apply this patch to port Makefile:

	cd /usr/ports/graphics/jpeg
	patch < /path/to/this/file

	Then use "make J_MAXMEM=nn" to limit memory usage to nn MBytes.
