I have just tried to build NetBSD 6.0_BETA i386 kernel with pcc and
found the compiler fails at a certain line.

$ -V HAVE_PCC=yes -V USETOOLS_PCC=yes tools
$ kernel=GENERIC
    sys/dev/usb/uslsareg.h, line 170: array size not constant

The offending line in "sys/dev/usb/uslsa.c" is;

    CTASSERT(offsetof(struct slsa_cpr, uniProvName[0]) == 60);
    At a glance the code seems ok.  Changing it to (more natural) form solved
pcc compile error.

    CTASSERT(offsetof(struct slsa_cpr, uniProvName) == 60);

It's a variable length array.  Not sure the original line is legal or not.
I don't see why it shouldn't be, though this seems a context issue.. I
have filed a bug report upstream for that, see
Fixed upstream now.
