Hello everyone,

QNX 6 is a POSIX-compliant UNIX variant, so porting curl was very easy.
Only two small changes to configure.ac were required in order to port
the latest curl (v7.10.7) to QNX 6.2.x (http://www.qnx.com).
The patch is attached to this mail.

Changes to support QNX 6.2.x
  - had to change a check before testing for -lnsl and -lsocket
    simultaneously. The configure system would forget that it had
    already found -lsocket to be suitable, otherwise.
  - had to move the check for IPv6 to below where -lsocket gets added
    to the default LIBS variable. The commands were not changed, only
    moved.
  NOTE: The libz.so included in QNX 6.2.1 is missing the zlibVersion()
    function. This will cause the compile to fail. It has already been
    corrected in QNX's internal cvs repository. Earlier versions
    (6.2.0) and future versions (6.3.x) should work fine. As a
    temporary measure it is possible to link against /usr/lib/libz.so.1
    which does include that function.

Thanks,
James
