Chuck,

While reviewing the libtool-patches list I came across a discussion[1] 
about compiler option support that gave me an idea.

The attached patch (against the latest 2.2.7a snapshot, not taking the 
other patch into account) should allow libtool to accept the 
-{shared,static}-libgcc flags and just pass them on to gcc.

Thoughts?


Yaakov
