This indeed helps directly pointing to the core of the problem: After
disabling the -Werror compiler flag (adding --disable-werror to the
function call configure.args-append inside the Portfile) the "port build
gdb" command still yields an error message in the file
"/opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_gdb/gdb/main.log":
:info:build /usr/bin/gcc-4.2 -O2 -I/opt/local/include -arch x86_64 -arch

:info:build gcc-4.2: -E, -S, -save-temps and -M options are not allowed

This seems to be an incompatibility with the multi architechture build in
the +universal variant, which is the only one available for gdb. Is there
any way to switch off the compiler flag "-arch i386"? or the other one?
and include a combination of single architecture builds with "lipo"? I
have no idea what the flags -M... are used for and who created the
Makefiles that contain them. Can these be circumvented?
