Wow, that's a very low limit.

I don't know.  Ask Sun?

system() is not a system call, it's a function that ends up calling
execv().  I can't see how using system() would make things any better.

Presumably there is some Solaris-specific thing you have to do to make
it accept all the arguments.  

distcc doesn't do anything special to linker invocations, it just runs
them locally.  If it works with plain cc it ought to work with
distcc.  

You could try running truss on Make to see how it exec()s the linker.
