[patch, rfc] Fortran async I/O support

[Nicolas Koenig]

Hey everyone,

Thomas and I have been working on adding asynchronous I/O to 
libgfortran. The patch is almost done, the only thing still missing is 
to link libgfortran against libpthread if it exists(which is for some 
reason necessary despite using __gthread) and deactivating it if 
libpthread doesn't exist (MinGW). At the moment it is still required to 
explicitly link against libpthread with -pthread when a program is 
compiled. Because of this we weren't able to run regression tests yet, 
since every single test fails.

It would be great if somebody else could try the patch and report their 
experiences. Also, if anyone knows how to add the whole conditional 
libpthread thing in the build script, a little help would be very welcome.

P.S.: I have a new email address, the old one has some problems.
