It appears that this is an issue with our configure tests with more
recent versions of GCC and cross-compiling (the error will not occur
when not cross compiling). Fixes have been applied for all the
upcoming releases. You can grab a nightly release from the 1.0
branch tomorrow and it should work. The nightly tarballs can be
downloaded from:

Releases from the 1.0 series will not properly cross-compile the
Fortran bindings - they must explicitly be disabled with --disable-
mpi-f77 in order for the configure script to complete. ROMIO on the
1.0 series has also not been tested to make sure it properly cross-
compiles. This has been fixed for the upcoming 1.1 release, although
you will have to run an external program on the target platform in
order to generate a seed file for some of the data we need in order
to cross-compile our Fortran bindings. We don't have documentation
on this just yet, but I can provide you with instructions if you need
Fortran bindings.

Hope this helps,
