Synopsis: small patch to libf2c/libIf77/configure.in for autoconf 2.50

State-Changed-From-To: open->feedback
State-Changed-By: bangerth
State-Changed-When: Sat Dec 21 09:08:39 2002
State-Changed-Why:
    The file for which you suggest the patch does not have the
    respective lines any more (the check for fcntl.h). Do you
    know whether this has moved somewhere else?
    
    Also, note that autoconf2.50 is, as far as I know, not
    presently supported, gcc still uses 2.13.
    
    Thanks
      Wolfgang
