One of the points of the exercise is to = be able to=20 build cygwin a little faster :]. To that end I'm building a=20 cross-toolchain.

I'm caught in the chicken-and-egg bit = with newlib=20 and gcc, and would appreciate some pointers - either to reading = material,=20 or to actions. (I recall Mumit's page being rather dated... thus my=20 question).

Steps so far:

grabbed the winsup tree, added bfd, = binutils and=20 opcodes all from cvs.

Built bfd, opcodes and binutils, with=20 --target=3Di686-pc-cygwin. installed that (/usr/local).

grabbed gcc from a cygwin mirror. = configured=20 with --target=3Di686-pc-cygwin.

That fails partway thrugh the build = (see the errors=20 below). I figure thats because no cross-headers have been installed. = So... I go=20 to build newlib, but cannot as, you guessed it, i686-pc-cygwin-gcc = doesn't exist=20 yet.

Hints ?
