[Bug preprocessor/25356] New: -MT appends target name, rather than replacing it

[igodard at pacbell dot net]

The -MT <name> option with -MMD is supposed to substitute <name> for the target 
in the generated makefile. In most cases it seems to do so. However (using the 
attached file,  which is a rename .ii file), the command:
    g++ -c -o accum.o -MMD accum.cc
produces the makefile:
    accum.o: accum.cc
as expected, but the command:
    g++ -c -o accum.o -MMD -MTfoo accum.cc
produces:
    foo accum.o: accum.cc
instead of the correct:
    foo: accum.cc
