From 1ea70d78ddbd7347df50103c4a915e140d913f9c Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Tue, 12 Sep 2000 20:54:13 +0000 Subject: 2000-09-12 Ralf Corsepius * aclocal/check-cxx.m4: Add AC_SUBST(CPLUS_LD_LIBS) * aclocal/prog-cc.m4: Cleanup comments, require RTEMS_ENABLE_GCC28, add automake conditionals RTEMS_USE_GCC, RTEMS_USE_GCC272. * automake/compile.am: Replaced. * automake/local.am: Remove building variant handling. --- automake/compile.am | 289 +++++++++++++++++++++++++++++++++++++++++++++++++++- automake/local.am | 44 +------- 2 files changed, 285
