RE: why is ./foobar target noted as foobar ??

[Mark Galeck (CW)]

I know the manual says "$@ is the _file_ name" but surely, this does not 
literally mean "only the file name not the directory".  For example, dir/foobar 
works.  Also dir/./foobar works.  Only "." at the very beginning does not work.

I get an unnecessary recompilation of the Linux kernel, and the diagnostics says

GEN     include/generated/bounds.h - due to include/generated/bounds.h not in 
./arch/powerpc/kernel/asm-offsets.s ./include/generated/asm-offsets.h 
./include/generated/bounds.h ./kernel/bounds.s


Well, the "filter" function operates on strings only and does not know anything 
about ./ being redundant, but, $@ appears to know about it.  Duh!

Hello,

With this makefile

./foobar:
                touch $@

make prints "touch foobar" .
