Hi,

This is intentional.  Guile 2.2 will use ELF as the format for .go
files, regardless of platform.

This is a portability problem in our test suite, and doesn't indicate a
problem with Guile itself.  Still, it would be good to fix it at some
point.

This is a _real_ bug, either in Guile or in Cygwin itself.  That "1"
should have been NaN.  One possibility is that Cygwin's 'fprintf'
doesn't handle NaN's properly.

Another more troubling possibility is that the code in
test-suite/standalone/test-conversion.c:ieee_init, also found in
libguile/numbers.c:guile_ieee_init, is not working properly under
Cygwin.  This could be a serious problem for numerics.

Were there any failures in 'numbers.test'?

    Thanks,
      Mark
