The relevant lines which cause an error are here:
extern int regexec (const regex_t *__restrict __preg,
const char *__restrict __string, size_t __nmatch,
line 544: regmatch_t __pmatch[__restrict_arr],
int __eflags);
With that being said, I guess this is a gcc extension-related error,
although I'm not sure how to fix it. Based upon lines 512 to 532, line 544
should be defined to "regmatch_t __pmatch[__restrict]". Perhaps pcc does not
support that extension inside an array, but does elsewhere? If
__restrict_arr expands to nothing, then we have regmatch_t __pmatch[], which
seems to be legal ANSI C. Does the binutils version provided with NetBSD
track upstream so perhaps I/someone could add a patch?

Good going :D!
As of 5 minutes ago, by setting HAVE_GCC=4, HAVE_PCC=1, MKGCC=no, and
MKPCC=yes, I've successfully compiled the current pcc in the NetBSD source
tree (using i486--netbsdelf-gcc) into my (global for all archs) NetBSD tools
directory. pcc has also just successfully built a kernel for my i486
machine.
I recall reading that build.sh can automatically determine which sources pcc
can compile and which sources it cannot, so I'll let pcc attempt to build
the userland and will report back if it fails on any targets that I cannot
fix (or skip) myself.
At some point, I'll try a dummy i386 build target and see if pcc can compile
gcc by setting HAVE_PCC=1, HAVE_GCC=4, MKGCC=yes, and MKPCC=no. Failing
that- since pcc doesn't have a fully functional C++ backend, I'll download
GCC 4.7.3 and try the same with a pcc on my host machine (since that's
unrelated to NetBSD, I'll join/post on the pcc mailing list).

I will try to import a new version later this week..
I have imported pcc-20140706 now, please report any problems in the usual
places (here for NetBSD build problems, or the PCC issue tracker for
compilation troubles)
