I have updated to revision 128003 and tried 'make bootstrap',

of failure in libgcc). I the tried a fresh install: new directory,
configure, and make, and it worked. So now
Hi all,
I have just recently had time to checkout and build the GCC plugin

After reading through the patches it seems simple enough, I just need to
create a shared library that defines the symbols:
pre_translation_unit
transfor

We are in the process of updating GCC/UPC's support for
the UPC dialect of C to version 4.2.0 of GCC.
GCC/UPC is described here: http://www.intrepid.com/upc.html

For example:
