            Bug ID: 219813
           Summary: wxgtk30 fatal error with ports built with gcc
           Product: Ports & Packages
           Version: Latest
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)
          Assignee: freebsd-ports-bugs at FreeBSD.org
          Reporter: xxjack12xx at gmail.com

ports built with gcc instead of clang will fail to start with a fatal error:

Fatal Error: Mismatch between the program and library build versions detected.
The library used 3.0 (wchar_t,compiler with C++ ABI 1002,wx
containers,compatible with 2.6,compatible with 2.8),
and your program used 3.0 (wchar_t,compiler with C++ ABI 1009,wx
containers,compatible with 2.6,compatible with 2.8).
Abort (core dumped)

This patch changes the fatal error to a warning to allow the programs to still
function.
