Subject: [Bug preprocessor/51341] make cannot detect head file change by dependency file with gcc 4.6.1 on ubuntu 11.10

I am a little confused. -MT will create .d file. Then make command will include
.d and re-compile if dependency file changes. The issue is that g++ 4.6.1
doesn't re-compile if I touch .h. Does this mean my test.d format is wrong? If
I need another -MT, what syntax it should be? Thanks a lot!
