           Summary: pgdijkstra - unwind_resume link error
           Product: CartoWeb
           Version: unspecified
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Plugins

When compiling pgdijkstra on OSX 10.4 (Xcode 2.4), there is a missing symbol error for 
unwind_resume.  This is a common problem on OSX with Xcode 2.2+ when linking C++ software with 
gcc instead of g++ (there was a similar problem in MapServer).  Linking -lsdtc++ is not enough, and 
using g++ is needed.

This one is tricky to handle in Postgres, since the link command is set by the Postgres pgxs.  I was able 
to get around it by adding this line after the include $(PGXS) line in the pgdijkstra makefile (mirroring 
what is set in pgxs.mk for Darwin):

LINK.shared = g++ -bundle -multiply_defined suppress

I don't know how else to handle this (I tend to do brute-force hacks).  The change happened in Xcode 
2.2, though the GC version did not change (4.0.1 I think).
