[m-dev.] diff: fix hg test problem

[Peter Ross]

Hi,


===================================================================


Estimated hours taken: 0.25

compiler/Mmakefile:
    The tests run on hg occur on a MS-DOS filesystem, so the chmod
    during .pp processing will fail, causing mmake to abort with an
    error.
