Hi, I'm working on a OpenJDK bug: the build fails with:

make[8]: execvp: /bin/sh: Argument list too long

I would like to know the value of ARG_MAX used on the buildd nodes.
Could you also suggest me how to change it on my system? I couldn't find
anything.

There are two problems with my patch: first, if the Makefile is executed
twice, the list of files to compile has doubled entries; second, the
list of files to compile is generated disregarding which target is being
executed. This is due to the fact that the $(shell ...) command is
evaluated before the target get executed. I couldn't find a way to fix
this, so far.

I cannot understand which problem you're trying to fix with this
if/wildcard construction.

Thanks, Giovanni.
