Hi Ali !

I'm having problems with long commandlines, too.
One workaround is the patch attached.
It changes the maximum action lenght for bjam actions to the 
(unrealistic) high value of 1.000.000. 

The builtin compiler limit (or better shell limit) is defined somewhere 
in the linux kernel sources. I guess its aroung 64k or so, but I cant 
find the location just now.

In my case, this works very well, except when commandlines exceed the 
shell limit. But even then the compiler fails gracefully.
For your information: I've got some 40 libraries and 6 exe's lying 
around here and it works reasonably well for now.

Yours,

Jürgen
