My previous dodge to make the GTK 1 headers work with modern compilers was to manually reset to -std=gnu89, which changed the semantics of 'inline' back to what glib.h was expecting. But that doesn't work now the PuTTY code base expects to be able to use the rest of C99, so instead I have to manually override the specific #defines that glib.h uses to know how 'inline' works. Also, moved that code in configure.ac out of the fallback branch that manually detects GTK1, so that it will fire even if autoconf is run on a system that still has the genuine GTK1 detection code. (Amazingly, one still exists that I have access to!) With that fixed, there's one more problem: the nethack_mode and app_keypad_mode flags in gtkwin.c's key_event() are only used in the GTK >= 2 branch of the ifdefs, so they should only be declared and set in that branch as well, on pain of a -Wunused complaint.
