pixman-ice.c

Hi, when compiling pixman for armv4t or armv5te with thumb enabled I've noticed
ICE, disabling thumb or O2 is enough to build it without ICE.

$ arm-oe-linux-gnueabi-gcc -march=armv5te -mthumb -O2 -c pixman-ice.c -o
pixman-ice.o
pixman-ice.c: In function 'prng_srand_r':
pixman-ice.c:113:1: internal compiler error: Segmentation fault
 }
