gdb/remote.c: In function 'int remote_set_syscall_catchpoint(target_ops*, int, int, int, int, int*)':
gdb/remote.c:2036:39: error: invalid conversion from 'void*' to 'char*' [-fpermissive]
catch_packet = xmalloc (maxpktsz);
^
gdb/thread.c: In function 'int do_captured_thread_select(ui_out*, void*)':
gdb/git/gdb/thread.c:1999:24: error: invalid conversion from 'void*' to 'const char*' [-fpermissive]
const char *tidstr = tidstr_v;
^
this patch fixes them by casting void * to the right type. I'll push
it in.

* remote.c (remote_set_syscall_catchpoint): Cast to char *.
* thread.c (do_captured_thread_select): Cast to const char *.
