Unless they were MFC'ed to -STABLE. THis is why you generally

that really means for this compiler on certain platforms, you

check how the modules do this..
also, look at the example device driver in -current
/usr/share/examples/drivers/make_device_driver.sh
that makes and then compiles a driver.

GCC from ports uses DWARF2 exception unwinding while GCC in src tree
uses sjlj exceptions. The exception handling code generated

Port has less patches. If you look at
/usr/src/contrib/gcc/contrib
in a related tangential note, i recently found (out of sheer irritation)
in less than an hour that several (including the latest) versions of GCC
-O and -O2 failed the paranoia test in different ways, to wit:
gcc -o paranoia paranoia.c

This is available for ia64. I think the speed returned by ia64 firmware

I do not fully understand the parts of GCC involved, so I need some
time to verify my initial diagnosis and to create a patch. In other
words - not yet :)

Hello,
I'm doing backups with pax(1). For indexing pax readable archives
I found it very useful to have the possibility to specify an arbitrary
strftime() formatstring that is used in verbose list mode.
The enhancement is filed as PR bin/35886.
Comments?

Folks,
I'll be visiting Germany for next week. My primary targets are
Hannover (for CeBIT show), Trier (and possibly Amsterdam, not Germany
though, but... :-).
Because of this trip I'll be rarely available at e-mail. If you will be
experiencing any problems with my recent locale/stdtime MFCs dur

Should be obtainable on Alpha and Sparc, and calculable on x86 (though it
will probably have to be calculated at the time the sysctl is read, since
it's variable).
