v2010.09 fails with: crc32.c:85:1: error: initializer element is not constant crc32.c:85:1: error: (near initialization for 'crc_table[0]') This appears to be fixed in later versions.
v2010.12 and v2011.03 fail with: ehci-hcd.c:59:3: error: initializer element is not constant

This is interesting, we've been using a Code Sourcey based 4.5.1 (hard to tell exactly what it is)
gcc version 4.5.1 (Sourcery G++ Lite 2010.09-55)
and it builds just fine.
