Summary: Double-colon rules sometimes behave like if they
were single-colon

Fixed Release: None
Triage Status: None
_______________________________________________________
Details:
When target of double-colon rule have characters escaped by backslashes, make
doesn't mark this rule as double-colon.
Simplest example of makefile illustrating the problem is:
a\ b :: ; @echo one
a\ b :: ; @echo two
Output of _make 'a b'_:
Makefile:2: warning: overriding recipe for target `a b'
Makefile:1: warning: ignoring old recipe for target `a b'
two
While the expected output is:
one
two
I'm using GNU Make 3.82 on Gentoo x86_64. Make built from the latest CVS also
has this issue.
After examining the source I made a trivial patch (attached) which fixes this
problem (tested on few projects and as far as I can see it doesn't break
anything).
