gdbserver: fix format string warning in win32-low.cc
When compiling on Cygwin, we get: CXX win32-low.o /home/smarchi/src/binutils-gdb/gdbserver/win32-low.cc: In function ‘int get_child_debug_event(DWORD*, target_waitstatus*)’: /home/smarchi/src/binutils-gdb/gdbserver/win32-low.cc:1459:17: error: format ‘%x’ expects argument of type ‘unsigned int’, but argument 2 has type ‘long int’ [-Werror=format=] 1459 | OUTMSG2 (("get_windows_debug_event - " | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1460 | "unexpected stop in 0x%x (expecting 0x%x)\n", | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1461 | ptid.lwp (), desired_stop_thread_id)); | ~~~~~~~~~~~ | | | long int /home/smarchi/src/binutils-gdb/gdbserver/win32-low.cc:52:11: note: in definition of macro ‘OUTMSG2’ 52 | printf X; \ | ^ /home/smarchi/src/binutils-gdb/gdbserver/win32-low.cc:1460:26: note: format string is defined here 1460 | "unexpected stop in 0x%x (expecting 0x%x)\n", | ~^ | | | unsigned int | %lx `ptid.lwp ()` is a `long` value, so it indeed needs the `l` size modifier. gdbserver/ChangeLog: * win32-low.cc (get_child_debug_event): Fix format string warning.
