Modified VPR at 2013-10-30, Thursday

When I modified vpr4.3, I found a strange phenomenon. In Makefile,
when I added -std=c99 in FLGAS, vpr4.3 running result on e64-lut4x4
was different with no adding -sta=c99. So why did it happened?
------------------------------------------------------------
Now I modifed try_place() function in place.c
