[cffi-devel] [PATCH] Expand body only once for uffi:with-cstring.

[Stephen Compall]

Got an explosion in CLSQL-PostgreSQL with a uffi:with-cstrings
expansion, as 7 strings makes 128 copies of the body.  On the theory
that the compiler can inline flets far easier than factor them, this
patch puts the body in an flet and calls the resulting function from the
two contexts `with-cstring' creates.
