../../src/gdb/linux-record.c: In function ‘record_linux_system_call’:
../../src/gdb/linux-record.c:1152:9: error: pointer targets in passing argument 3 of ‘regcache_raw_read_signed’ differ in signedness [-Werror=pointer-sign]

I believe the read_signed calls are correct, and the variables are in
the wrong.
Tested on x86_64 Fedora 17.
