This *may*, I repeat *may*, be relevant.  I dunno about now, but in the 
past there have been times when cygwin would build fine on Chris' 
linux-based cross compiler setup, but wouldn't build natively.  (and 
vice versa, IIRC).

Err, kinda.  The sources are really set up for building from a CVS 
checkout -- which pulls the w32api stuff along with it.  But, if someone 
were to try to build from the packaged -src tarballs, they would need to 
either pull the w32api*-src tarball also, or create the symlink you 
mention.

Perhaps we do need an "Idiot's Guide to Compiling Cygwin".  Then again, 
maybe we don't really WANT a bunch of challenged people compiling cygwin 
from scratch...  8->

Bzzt.  Every cgf-built release, which is to say all of them, are built 
on a linux box.

Now hold on -- this is probably my fault.  I dunno if the wrapper 
scripts handle both cases.  If they don't, then there are a number of 
workarounds:
   #1: don't do that.
   #2: export PATH=/usr/autotool/stable/bin:${PATH}
   #3: send me patches to fix the wrappers

Or maybe it ISN'T my fault...

Sure, but cgf can be forgiven for playing the house odds -- the deck is 
stacked, you know.
