Strange behaviour of <big>

[Alvise Belotti <nospam@thanx>]

Hi all,
I have a strange problem with gfont, <big> actually.
I'm using <big X> in various pages.
For semplicity I've defined a variable GFONT_BASE in my .wmlrc
-D GFONT_BASE~images/
But this way all the images are named images/.gfontXXX.gif, regardless
the page which they belong, thus leading a big mess in my pages.
Obviously I'm missing something, but what?
I've tried -D GFONT_BASE~images/%BASE, but this is not expanded.
Neither 
<define-tag big>
<gfont face="TimesBold" size=+3 align=left base=%BASE crop>%0</gfont>
</define-tag>                              ^^^^^^^^^^
works.
Any ideas?
Tia
