Portable prefix pattern rules

[Brian]

I am trying to find a portable way to replace this rule as given in AutoQt 
[1], which the autotools warn against using:

 SUFFIXES = .moc.cpp

%.moc.cpp:%.h
        $(MOC) -o $@ $<


The following doesn't seem to work:

SUFFIXES = .moc.cpp

.moc.cpp:.h
        $(MOC) -o $@ $<

The only other alternative I see is to enumerate a rule containing the 
actual file names for every single .h to .moc.cpp conversion, of which there 
are hundreds.

Cheers,
Brian Mingus
