with XINPUT_GXI defined gdk.c will not compile because at line 340
equal_pos is not declared in the line:
	gdk_input_gxid_port = atoi (equal_pos + 1);

1) my use of XINPUT_GXI may be incorrect for my system!?
2) my very fast fix and totally untested workaround is to change
   line 340 of gdk.c as follows:
	gdk_input_gxid_port = atoi (option);
   this seems consistent with the code in the other #ifdef blocks
   in this function call (gdk_init_check).

i'd appreciate a quick email ras@acm.org note if my selection of
XINPUT_GXI is the correct choice for a stock solaris 2.5 cde 1.0.x

thanks

hope the work-around is corrent and helpful
