You must be referring to newlib if you are talking about Makefile.am.
newlib has its own mailing list newlib at sourceware PERIOD org .
You'll need to talk to the maintainer of newlib if you are adding a new
function there.

Please look at the Makefile.

The standard answer: debugging symbols.

Under windows, if you install over top of an in-use dll, you are asking
for problems. You really do have to copy cygwin1.dll manually, using
windows commands.
