	../../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.

	* linux-record.c (record_linux_system_call) <gdb_sys_msgrcv,
	RECORD_MSGRCV>: Pass a signed variable to
	regcache_raw_read_signed, instead of an unsigned one.
