Hi !

Sorry for the direct ping, but after 9 days:

Any ideas yet ? Or should I open a trac ticket ?
 
I've attached the output of running "bjam --debug-configuration" on 1.34 
and 1.35 (branches/release).
The relevant diff is:

 warning: toolset gcc initialization: can't find tool windres
 warning: initialized from
-notice: using rc compiler :: <toolset>gcc-4.1 :: as
+notice: using rc compiler :: <toolset>gcc-4.1 :: windres
+notice: will use '/home/hunold/bin/gcc-4.2.sh' for gcc, condition 
<toolset>gcc-4.2

So that 1.34 clearly uses "as" and 1.35 tries to use "windres".
 A clear regression to me.

Yours,

Jürgen
