src/models/Makefile.am breaks make distcheck

[ohl]

The following resonable code in src/models/Makefile.am

if !OPTIMIZATION_FOR_PARFILES
.f90.o:
	$(FCCOMPILE) -O0 -c -o $@ $<

.f90.obj:
	$(FCCOMPILE) -O0 -c -o $@ `$(CYGPATH_W) '$<'`

.f90.lo:
	$(LTFCCOMPILE) -O0 -c -o $@ $<
endif

produces the following broken code src/models/Makefile.in:

distclean-compile:
        -rm -f *.tab.c

@OPTIMIZATION_FOR_PARFILES_TRUE@.f90.o:
        $(FCCOMPILE) -c -o $@ $<

@OPTIMIZATION_FOR_PARFILES_TRUE@.f90.obj:
        $(FCCOMPILE) -c -o $@ `$(CYGPATH_W) '$<'`

@OPTIMIZATION_FOR_PARFILES_TRUE@.f90.lo:
        $(LTFCCOMPILE) -c -o $@ $<

mostlyclean-libtool:
        -rm -f *.lo

because the commands for distclean-compile will be augmented by calls to the fortran compiler. Consequently make distcheck fails:

This appears to be a automake bug.

With the version of [1504], Automake should handle this correctly.
