This appears to be caused by bsdgrep. :-/ The build for lib/libsysdecode
uses a shell script, mkioctls, to generate a ioctl.c file at build time.
This script contains the following fragment:
ioctl_includes=$(
cd $includedir
find -H -s * -name '*.h' | \
egrep -v '(.*disk.*|net/pfvar|net/if_pfsync)\.h' | \
xargs egrep -l \
'^#[ ]*define[ ]+[A-Za-z_][A-Za-z0-9_]*[ ]+_IO[^a-z0-9_]' |
awk '{printf("#include <%s>\\n", $1)}'
)
The idea is that all headers are searched for defines of ioctl macros,
which start with _IO. The -l option to egrep is used to print only the
matching filenames, not the matched content itself.
However, this option seems to be broken in bsdgrep, as it *does* display
the matched content:
$ gnugrep -l printf /usr/include/stdio.h
/usr/include/stdio.h
$ bsdgrep -l printf /usr/include/stdio.h
#define __SSTR 0x0200 /* this is an sprintf/snprintf string */
/usr/include/stdio.h
I did a quick check, and this option seems to have been accidentally
broken by r317703 [1] ("bsdgrep: fix -w flag matching with an empty
pattern").
Ed, Kyle, any idea where the problem might be?
