u_int32_t causes cross-compile problems [PATCH]

u_int32_t causes cross-compile problems [PATCH]

I came across this C standards issue while cross-compiling the Linux 
kernel with gcc on Solaris. The file gen_crc32table.c uses the 
non-standard type u_int32_t. It's possible that the host machine's 
sys/types.h does not define u_int32_t. The attached patch replaces 
u_int32_t with the POSIX standard uint32_t and includes POSIX inttypes.h 
instead of sys/types.h.

Please CC me when replying.

Pratik.
