Hi,I managed to get dia for mac os x compiled and running. here is a list of issues I found with it: First off gcc4 on mac os X complains that parse_path is delcared as non-static and defined as static. This patch fixes that:

According to the libtool manual, these two options should never be used together. -module is used to link a library which is going to be opened with dlopen. -export-dynamic is used when you need to use symbols from your executable to resolve dependencies in your dlopened module. Which means, if used correctly, -module appears on the link command for the dlopened library, and -export- dynamic appears on the command to link the executable which will be dlopening said module, and only if necessary. Futhermore, even when using -export-dynamic is used, you don't need to link directly with a dlopenable module (that is the point, even), which according to app/ Makefile.am, you are.
However, it just so happens that on linux, and probably other systems, the process of creating a dlopenable module is exactly the same as the process of creating a dynamic linker shared library. On mac os x, however this doesn't work (and libtool will actually inform you that this is non-portable, at least when run on mac os x).
This patch modifies lib/Makefile.am to have the correct libtool flags to properly compile on mac os x Given all these details I suspect that this fixes compile problems on other platforms as well.

I've successfully compiled and run dia 0.94 on mac os 10.4.2, using
fink versions of libtool 1.5.10, autoconf 2.59, and automake 1.9.4 (I
actually regenerated configure using these tools, I am not sure if
this is necessary).
