Re: [Lib2geom-devel] Warnings compiling lib2geom SVN

[mgsloan <mg...@gm...>]

The issue is the error on min.  The warnings are fine.

This is likely due to some sort of compiler/libs incompatibility,
though your list looks fine.  This is probably why we used to have
custom min/max.  Anyway, I've re-added custom Min/Max to svn.  Might
as well, as it might help with compatibility in the future.

Hope that fixes it,
Michael Sloan
