Solaris builds with the CC 5.8 compilers (used for jdk6 update builds) fail while compiling adlc:

EVALUATION

Since some of the errors are in system headers we can only disable the "+w -errwarn" on SS11 and below.

There are three ways to fix this problem:

1. Remove the "+w -errwarn" again, but I would like to keep it as it found a number of bugs in ADLC when I switched it on.

2. Disable "+w -errwarn" in adlc.make for SS11 and below.

3. Enable "+w -errwarn" in sparcWorks.make for SS12 and above for the whole HotSpot build and try to fix all errors coming up.

I'd like to do 3., but it seems not to be trivial.  Since there are already a couple of "foo hides the function bar" when compiling the first file and I'm not sure what else is popping up.
