And, I missed that little bit of makefile. Thank you for
pointing it out. I'll drop the patch for now.
Is there a practical, reusable mechanism to apply a
set of CFLAGS to a list of objects derived from a make
variable without using eval? Florian raised this issue
earlier and received no feedback.
Likewise, the same question applies to my proposed
patches to refactor the _Complex wrappers.
