(Division by zero is undefined in ISO C so it's still OK to check for it
here.) Add a new `-e' flag to get the old, more useful behavior.
in each cycle, with a tunable max cycle count defined in fdreg.h.
This is said to fix the problem on some Compaq hardware (and perhaps
on other machines using the Natsemi PC87317 chip) where the fdc(4)
driver failed to operate at all.

make sure it's a correct operation for devfs, do it only in the
ISLASTCN case. If we don't, we are assuming that the final file will
be in devfs, which is not true if another partition is mounted on top
of devfs or with special filenames (like /dev/net/../../foo).

it into an "#ifdef INET6" block. This caused a (harmless but annoying)
EINVAL return value to be sent even though the operation completed
successfully.

The problem is the GCC driver now turns STANDARD_EXEC_PREFIX into a relative
path -- "<basename argv[0]>/../../libexec" for our normal install location.
However, in the middle of `buildworld' we need
"<basename argv[0]>/../../../../libexec" due to the prefix we tell the GCC
driver. But either the GCC driver is buggy, or we are confusing it, as it
tries to exec "<basename argv[0]>/../../libexec/cpp0" as if it were installed
in the normal place (but isn't).
MD_EXEC_PREFIX is still absolute, so I'll use that for now. I would like to
later make it so MD_EXEC_PREFIX is set only for `buildworld', as
MD_EXEC_PREFIX is also in the search path for libraries. Don't ask me why!
Another way is to add ${OBJFORMAT_PATH} (as set in CROSSENV) to the PATH
in src/Makefile.inc's WMAKEENV.
- Axe -fdata-sections as turning it on or off makes no difference. If
it did make a difference it would serve to bloat boot2 even further with
extra padding.
- Axe -fforce-addr. This gets us 32 bytes so we are down to only being
64-bytes over.
We still can't compile this with gcc 3.1. The problem seems to be that
the -fno-align-foo options don't actually work. Comparing the new and
old output it turns out that gcc is 4-byte padding all the functions and
labels and what not despite the passed in arguments thus adding the
unfortunate bloat to boot2.
