description:
Import latest PCC snapshot 20140706; it has been over two years since
the last import, and some build framework has been changed so this
makes it easier for people to work with later versions.
The full list of changes in the meantime are available at the PCC
CVS server, and the bugs fixed are detailed at the PCC bug tracker,
but in summary, new features added are a C++ front end, m68k support
and unicode support.
and bugs fixed in the areas of the register allocator, floating point,
attributes, long long arithmetic, PIC support and code sections (for
shared libraries) among others.
This version compiles the vast majority of the NetBSD sources on i386,
and bug reports are welcome at the PCC JIRA server.
