update to pcc snapshot 20160208. Rather than provide the full
list of changes, they can be found at

http://pcc.ludd.ltu.se/fisheye/changelog/pcc

Along with numerous bug fixes, the highlights might be a rewrite
of the CPP parser, updated backends for arm, pdp11, m68k, vax and
mips along with new backend for 8086. PCC now builds itself as a
2-pass compiler. There have been fixes for use with musl, C11
support added and use of UTF8 internally. PE/COFF target was fixed,
and Minix target added.

branches: 1.1.1.1.2; 1.1.1.1.6;
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.
