Created attachment 476992 [details] Backport from r162990 upstream Description of problem: gfortran no longer recognizes the -M* options in gcc-4.4. This is a regression in gcc-4.4 caused when gfortran moved from cc1 to libcpp for its external preprocessor. The feature works correctly in RHEL-5. The bug has been documented and fixed upstream: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43954 How Reproducible: Always Steps to Reproduce: root@gncc mtest # cat mtest.F #include "mtest.h" x(1) = 2 print 10, x(1) 10 format(' Hello World, x(1) =', i5) end root@gncc mtest # cat mtest.h integer x(10) root@gncc mtest # gcc -M mtest.F Actual Result: root@gncc mtest # gcc -M mtest.F f951: warning: command line option "-M" is valid for C/C++/Java/ObjC/ObjC++ but not for Fortran Expected Result: root@gncc mtest # gcc -M mtest.F mtest.o: mtest.F mtest.h
This has been committed to upstream 4.4 branch on Date: Sun Aug 8 01:59:15 2010 therefore it is in RHEL6.1 gcc-4.4.5-5.el6, which is currently based on 20110117 snapshot.
