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