The odd thing is that even though it complains, it still generates the
correct Makefile in the first case:
SYMFILES = $(srcdir)/uni.h $(shell $(CC) $(CFLAGS) -E

Does automake need to be $(shell ...)-aware?
The warning is:
src/q2931/Makefile.am:21: shell $(CC: non-POSIX variable name
src/q2931/Makefile.am:21: (probably a GNU make extension)
and automake is entirely correct; you are using a GNU make extension.
Ideally, you should avoid the use of such non-portable extensions, but
if it is not feasible, you may disable the warning by passing
-Wno-portability to AM_INIT_AUTOMAKE.
Since I only needed it in the child Makefile, I stuffed it into
src/q2931/Makefile.am as:
AUTOMAKE_OPTIONS = -Wno-portability
and that fixed it. Thanks!!!!
