Expansion of $source (bcc static lib support)

Dear all, dear Bram,

I have posted some times ago for a bcc support of static library build.
I have had now some time to try to implement and use it, I face one
problem - as the building path is build-nt/..., the commandline refuses
it so, that afaik I have to write the tlib.exe command like that : 

tlib lib\mylib.lib, "build-nt\...\file1.obj", "build-nt\...\file2.obj"

to have the right expansion, I have the following statement : 

":sys $AR $target, $source"

and I transform it into 

":sys $AR $target ,\"$*source\" "

to get it into quotes. It doesn't work and I get something like 

tlib lib\mylib.lib ", build-nt\...\file1.obj" ", build-nt\...\file2.obj"

I have tried some other combinations without success. Is it possible?
Here is my (very experimental tools/bcc.py file).
Thanks,
fred
