------- Comment #13 from howarth at nitro dot med dot uc dot edu 2010-09-04 03:39 ------- Reverting both libgcc/configure.ac and libdecnumber/configure.ac and regenerating these files is insufficient as well to eliminate the regressions on darwin. Looking at the remaining changes in gcc/configure.ac it is obvious way this change badly breaks non-linux targets.
http://gcc.gnu.org/viewcvs/trunk/gcc/configure.ac?r1=163815&r2=163814&pathrev=163815 The author cut out two sections from gcc/configure.ac and pasted them together in dfp.m4. The intervening section... dfp=`if test $enable_decimal_float != no; then echo 1; else echo 0; fi` AC_DEFINE_UNQUOTED(ENABLE_DECIMAL_FLOAT, $dfp, [Define to 1 to enable decimal float extension to C.]) is now moved to the end, breaking the original logic. This is without even considering the other subtleties in the same code from libgcc/configure.ac and libdecnumber/configure.ac that has been simply ignored. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45524
