the typical configuration for most device drivers and
standalone modules; only infrastructure modules or those with
special requirements typically need to export symbols.
Don't print the objcopy commands as they are run when converting

This can probably explain a number of weird quota related behaviours.

traps on the first instruction of signal handlers.
In trap.c:syscall(), fake a trace trap if the single-step flag was set
on entry to the kernel, not if it will be set on exit from the kernel.
This fixes bogus trace traps after the last instruction of signal handlers.
gdb-4.18 (the version in FreeBSD) still has problems with the program in

fixed in gdb-5.1 (the distribution version).

the interface names returned by that ioctl in further ioctls,

simplifying the module linking process and eliminating the risks
associated with doubly-defined variables.
Cases where commons were legitimately used (detection of
compiled-in subsystems) have been converted to use sysinits, and
any new code should use this or an equivalent practice as a
matter of course.
Modules can override this behaviour by substituting -fno-common
out of ${CFLAGS} in cases where commons are necessary
(eg. third-party object modules). Commons will be resolved and
allocated space when the kld is linked as part of the module
build process, so they will not pose a risk to the kernel or
other modules.
Provide a mechanism for controlling the export of symbols from
the module namespace. The EXPORT_SYMS variable may be set in the
Makefile to NO (export no symbols), a list of symbols to export,
or the name of a file containing a newline-seperated list of
symbols to be exported. Non-exported symbols are converted to
local symbols. If EXPORT_SYMS is not set, all global symbols are
currently exported. This behaviour is expected to change (to
exporting no symbols) once modules have been converted.
