X-Git-Url: http://git.sourceforge.jp/view?a=commitdiff_plain;h=e8b751650f58d4d993b6b0b6d870747529a8c636;hp=02843127e45a55f57a9b8f90c3b3204235da7a55;p=pf3gnuchains%2Fgcc-fork.git

Support 64-bit libjava multilib for i?86-linux

	* configure.ac (i?86-*-linux*): Set SIGNAL_HANDLER_AUX.
	* configure: Regenerate.
	* include/i386-signal.h: Wrap in __i386__, include
	java-signal-aux.h otherwise.
