[patch] gdbserver: variable might be clobbered by ‘longjmp’

[Jan Kratochvil]

Hi,

gcc -flto with gcc-4.7.0-5.fc17.x86_64 produces
server.c: In function ‘main’:
server.c:2607:7: error: variable ‘multi_mode’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered]
server.c:2608:7: error: variable ‘attach’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered]

probably obvious, I will check it in.


Thanks,
Jan

	Fix gcc -flto compilation warning.
	* server.c (main): Make variable multi_mode and attach volatile.
