Re: Building PCC for "tools" is broken (missing symbol __USE)- PCC bug or NetBSD source tree error?

PCC is getting there...
I have applied the diff to the PCC source tree inside the NetBSD source. Although the source tree has been updated since Iain first imported pcc-20140706, the patch applied cleanly, minus one hunk that I for some reason don't think is a big deal :P:

It would be rather odd if a comments patch caused compilation to fail XD.
As of applying this patch, regex.c in libiberty now compiles correctly (see 7/24/2014 at 10:15 PM EDT for the error re: register):

Unfortunately there are now two errors- one compiling the kernel, and the other compiling userland... The error in the kernel happens at assym.d (Ignore the kernel name- it's a slightly modified GENERIC_TINY). I'm not sure what happened here, but it appears the preprocessor doesn't like being invoked with the following command line. The only single-period I see is "-I.", and that works when the preprocessor by calling it directly:

The error in userland happens at libatf-c++, complaining about a missing C++ compiler. It seems that groff is no longer the only C++ code in the source tree. Iain mentioned that UNSUPPORTED_COMPILER.pcc= can be set to skip tools that the compiler cannot build. Since pcc does not have complete C++ support, this is what I'll probably do (I have not tested this yet- I'm stopping at errors as I find them to notify the mailing list).

In any case, it seems that pcc is getting closer to being able to compile the NetBSD source tree. Perhaps it'll be ready in time for 7 release at this rate (I'll file a problem report with the relevant patches if I can get a GENERIC i386 kernel to build). I'll be on standby ready to apply patches from the main PCC source tree if need be, and be I'll sure to send a diff of my PCC tree (which has patches from the main source tree applied) vs the one currently in NetBSD.
