well, your patch shouldn't do anything when setting the alpha-value on 
any machine, since alpha-blending is turned off by default.

apart from that:

gem-0.90.1 for w32 is build with FTGL support; the changelog of FTGL 
says (FTGL-1.0b3; August 8 2001)
<snip>
Pixmap fonts can now be in colour. It uses the current colour when the 
font is CREATED. This isn't ideal but is better than the alternatives.
</snip>

it furthermore says (FTGL-2.1.2; 11 December 2004)
<snip>
hanged the way the colour is specified for Pixmap fonts. It can now be 
done per string rather than at start up as previous.
</snip>

probably this is related to your problem (i don't remember which 
FTGL-version is used to link against gem-0.90.1; but according to the 
date it might well be that i used an earlier version)
