I've applied, after doing the following changes:

    [Thomas:
     - change the download location to use downloads.sourceforge.net
     - turn the patch into a Git-formatted one, since upstream uses Git as
       its version control system
     - as noticed by Khem Raj, a C99 compiler is needed for the bool type,
       so added AC_PROG_CC_C99 to configure.ac, and consequently added
       IPERF_AUTORECONF = YES.
     - removed two <pkg>_CONF_ENV variables related to the bool type, they
       were added by an older commit
       e13ac0ec8788092c6508636da94fe0198c18dffd back when we had a
       config.cache shared between packages (which is no longer the case
       today)]

If you could submit the updated patch upstream, it would be good.
Thanks a lot!

Thomas
