makefile problems

[Max Heffler @ Landmark Graphics]

Has anyone else noticed the following problem with make under AUX 1.1:

If a dependency of the following type is used:

lib.a: lib.a(f23456789012.c)

.c.a:
	cc -c $<
	ar vr $% $*.o

The file is always out of date, so the make always performs the compile.
A .c.o rule seems to work with 14 chars. but not the .c.a rule.
Any known fixes/patches?

Thanx in advance.
