From 2c0a7840a28ae696e80e73157856d7a049fdf6c7 Mon Sep 17 00:00:00 2001 From: Gaetan Nadon Date: Sun, 15 Dec 2013 19:49:59 -0500 Subject: xtrans.m4: remove AC_TYPE_SIGNAL and Imake SIGNALRETURNSINT Assume signal handlers return void, as C89 requires Drops use of autoconf's obsolete AC_TYPE_SIGNAL and Imake's even more obsolete SIGNALRETURNSINT. None of the modules including xtrans.m4 uses RETSIGTYPE from autoconf.
