the generation of the error was added in rev.1.44. The .error directive
gives fatal errors, so stale /etc/make.conf.local files must have been

Intel C/C++ compiler (lang/icc) to build the kernel.
The icc CPUTYPE CFLAGS use icc v7 syntax, icc v8 moans about them, but
doesn't abort. They also produce CPU specific code (new instructions
of the CPU, not only CPU specific scheduling), so if you get coredumps
with signal 4 (SIGILL, illegal instruction) you've used the wrong
CPUTYPE.
Incarnations of this patch survive gcc compiles and my make universe.
I use it on my desktop.
To use it update share/mk, add
/usr/local/intel/compiler70/ia32/bin (icc v7, works)
or
/usr/local/intel_cc_80/bin (icc v8, doesn't work)
to your PATH, make sure you have a new kernel compile directory
(e.g. MYKERNEL_icc) and run
CFLAGS="-O2 -ip" CC=icc make depend
CFLAGS="-O2 -ip" CC=icc make
in it.
Don't compile with -ipo, the build infrastructure uses ld directly to
link the kernel and the modules, but -ipo needs the link step to be
performed with Intel's linker.
Problems with icc v8:
- panic: npx0 cannot be emulated on an SMP system
- UP: first start of /bin/sh results in a FP exception

- Added INTERNALPROG (by analogy to INTERNALLIB) for programs which are
built only for its side effect and shold not be installed.
- do not use PROG for what's not a real C program,
- use sys.mk transformation rules where possible,
- only create the "machine" symlink on AMD64,
- removed MAINTAINER lines in individual makefiles,
- added the LIBSTAND defitinion to <bsd.libnames.mk>,

CFLAGS in all cases, but POSIX requires a default of -O. Adding
-pipe unconditionally still is still broken for non-gcc compilers
in the non-POSIX case.
- Added missing NOCRYPT and NO_OPENSSL checks for Kerberos.
- Don't depend on -lcrypto and -lcrypt in pam_ssh to resolve
dependencies in pam_krb5 and pam_ksu -- the former may not
be compiled at all if NO_OPENSSH knob is enabled.
- Added missing -lcrypt to pam_ssh dependencies.
- Moved librpcsvc after libypclnt.
(The last two aren't strictly speaking necessary to resolve
the dependencies of static versions of pam_ssh and pam_unix,
respectively, but they correspond to dynamic dependencies
of libssh and libypclnt, and are put here for consistency.)

This is known to fix compilation of s_log1p.o in lib/msun on i386,

marked broken) instead of legal s_log1p.c which is in CFLAGS. The

This can be useful in some random cases where it's necessary to

that inner .for loops are not real loops but a tricky form
