The "make" released with 2.1 doesn't appear to ever do much with the
"$<" makefile variable when the target doesn't have a suffix; if I do
foo: foo.c
echo $<
I get
% make
echo
%
The only difference in "make" from 2.1 to -current is
revision 1.5

Fix the :S modifier to substitute in each word of the variable, according
to the description in the manpage. g flag means "replace every occurence
in each word", and its absence means "replace first occurence in each word".
Previously, absence of the g flag was implemented to mean "replace first
occurence found in all words, and then stop replacing", which was incorrect.
which I don't think applies to $<.
/sys/compile/LINT/Makefile ends up using $< when building linux_genassym:
linux_genassym: $S/i386/linux/linux_genassym.c $S/i386/linux/linux.h
${CC} ${CFLAGS} -o $@ $<
which confuses cc mightily since it replaces the $< with an empty string.
Am I doing something wrong, or is this wrong? (I didn't complain when I
first noticed it last week since I assumed I was doing something wrong or
someone else would notice it).
I have a shell script that tries to build LINT nightly and sends me email
if it fails. Perhaps this output should go to the mailing list?
(I will have a hard time keeping my vow to always build LINT before
committing anything if LINT is always broken).
