 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.
