There is another non-portable feature in that exact same test.

I sent a patch for it a few weeks ago, if someone would like to review that
at the same time.

--- forward ----
Cygwin is not completing the "linker read-only and
read-write section mixing" configure test. It aborts with:

conftest1.s: Assembler messages:
conftest1.s:1: Warning: rest of line ignored; first ignored
character is `"'

It seems that Cygwin's "as" doesn't like double-quotes
surrounding it's section names.  This in itself may or may
not be a bug, but it that is not what this particular
conftest is testing.  Regardless, from what I can gather
from the gas docs not having the quotes should be OK on all
targets.
