>Description:
If one compiles a source file using the -MD option to create
a ".d" dependency file and specifies an output file, then if the source file contains an error, gcc-3.2 will delete the dependency .d file and leave the .o object file. Once the failure is corrected, Make may no longer have the complete dependency information to recognize that the object file needs to be rebuilt.  Gcc-2.95 did not delete
the dependency file upon compilation failure.
