           Summary: -current broken on AIX: conflicting types for
                    gai_strerror
           Product: Portable OpenSSH
           Version: -current
          Platform: Other
        OS/Version: AIX
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Miscellaneous
        AssignedTo: openssh-unix-dev at mindrot.org
        ReportedBy: dtucker at zip.com.au


Recent additions to fake-getaddrinfo cause compile errors on AIX.

The new code defines gai_strerror as returning "const char *".  AIX 4.3.3 
and 5.1 (and RFCs 2133 and 2553) define it returning "char *".

This mismatch causes the following error.  The definition of gai_strerror is 
buried in /usr/include/netdb.h, there doesn't seem to be any easy way of 
excluding it.
