Compiling NetBSD using PCC- Round 2

["William D. Jones" <thor0505%comcast.net@localhost>]

Resending my previous message to current-users, as Majordomo decided it 
wanted to eat my mail when I tried sending this to both PCC's and NetBSD's 
mailing list simultaneously...

===

Hello all,

After taking a few months off, I decided to try (cross-)compiling a
kernel/userland using PCC. Unfortunately, there are still a few kinks to be
worked out, but perhaps someone here who understands PCC internals and the
very verbose output of build.sh can give me pointers in the right direction?

Currently, when building a GENERIC i386 kernel, I get a decent amount of the
kernel compiled before the kernel source dependency generation bombs when
trying to invoke the preprocessor. I'm not sure what is causing this error,
but I do find it interesting that nbmkdep doesn't have any input source
file, like previous targets (e.g. nbmkdep takes as input swapnetbsd.c to
create GENERIC/swapnetbsd.d and swapnetbsd.c in
OBJDIR/sys/arch/i386/compile/GENERIC. The error output shows no input C file
to mkdep when ./build.sh fails, and this only occurs for builds using PCC.

Does anyone have any idea what might be causing this? Perhaps my mk.conf is
interacting badly with deciding which kernel source files to use to build
the kernel? I have pasted the full error as follows, in addition to the
command line and mk.conf I used.
