AGG: missing truetype label outlinecolor on Windows/VC8

[Andreas Albarello]

Folks,

some strange things are happening here with MapServer 5.0 beta 4 (as 
well as all the previous betas) regarding AGG truetype label rendering.

For instance, when compiling MapServer with VC8, more precisely Visual 
C++ 2005 Express SP1, against agg 2.4 (compiled with the makefile 
provided by Jeff McKenna) and libfreetype 2.2.1, both compiled with VC8 
as well, my truetype labels suddenly have no outlinecolor anymore. When 
I change the outputformat back to use GD for rendering, everything is 
fine. I can reproduce this behavior on two different machines, even 
through shp2img with a basic mapfile having just an annotation layer.

Funny thing is, and I came up with this more by chance than anything, 
when I disable compiler optimizations by tweaking Makefile.vc to pass 
/Od instead of /Ox to the compiler for mapagg.cpp only (all other files 
and libraries, including agg, are compiled with optimizations on) I'm 
able to get my outlinecolors working again. This smells a lot like a 
compiler bug to me. If some Windows folks out there can perhaps confirm 
this, I'm ready to file a bug report on this, in order to at least tweak 
the Windows makefile (well, I guess that's most likely the only thing we 
can do about this).

Best regards,
