I have dropped rev 1.28 of mt_allocator.h into the gcc-3.4.0 source
tree, built it and used it to build both the small test program and
the original real application that was having problems.  All seems
well so far.  This is for sparc-sun-solaris2.8.

I will provide further feedback on i386-pc-solaris2.8 when I get there
:), and I may be able to try sparc64-sun-solaris2.8, too.

Thanks for your help!
