Something like
IFS=:; for d in a:b; do echo $d; done
works for Sun's /bin/sh, but not for Bash 2.05b (even if you
use --posix). The Bash folks say that this has been done to
fix a security hole.
I have another concern: In your version $(srcdir) gets
a higher priority than the $(VPATH) set in Makefile.am. If
Automake instantiates the suffix rules to generate *.o files,
then this is different, AFAICS.
So how about this?
`IFS=:; x=":$(VPATH)"; \
for d in $$x; do \
test -n "$$d" && d=$$d/; \
test -f "$$d"%SOURCE% && echo "$$d" && break;
done`%SOURCE%
It allows the writer of Makefile.am to completely ignore
$(srcdir), if he wants to.
