The toplevel configury of src is, as all you developers know, a mess.
I've been trying to clean it up over at gcc. I ran into a bizarre
situation and was told that Cygwin people might be able to help clear it
up.
Suppose you're building a combined tree of some sort with target
*-*-cygwin*
powerpc*-*-winnt*
powerpc*-*-pe*
ppc*-*-pe
According to the comments, newlib is 'always' built. This is false.
If --without-newlib was specified and host=target, the newlib in the
tree is not built.
If --without-newlib is specified and host!=target, the newlib in the
tree is built, but it isn't used; --with-newlib isn't passed to
subconfigures, and nothing is added to FLAGS_FOR_TARGET for newlib.
This is almost certainly wrong behavior.
How should --without-newlib behave when targeting *-*-cygwin* (and the
others)?
Should it mean "Don't build or use the newlib in the tree; use installed
libs and headers, or the ones specified with --with-libs and
--with-headers"?
Should it be illegal, and give an error message?
Should it be unspecified, in which case I can change its behavior for
code cleanliness?
Please send responses to neroden AT gcc DOT gnu DOT org. Thanks.
