Ask and ye shall receive... Not quite as general purpose, but still...

$ VAL=113
$ sed -e '/[	 ]'$VAL'	/!d' -e 's|^.*/\* \(.*\) \*/.*$|\1|' \
/usr/include/asm/errno.h

Just change the number in the variable to change the errno you find.  You
could also wrap it in a shell script and do the var sub in there, but that'd
kill the fun.

Note also that the whitespaces in the delete command are a mix of tabs and
spaces - a tab and a space in the brackets, and a tab after $VAL.
