Happens also with 4.2.1 but not with 3.3.6.

Subject: Re:   New: gcc-4.3.1: stripping trailing backspace from 
 args fools gcc

What exact problem are you trying to report here?  Quoting a space with
\ to the shell causes it to not split the arguments into two words,
which means gcc receives an argv[1] = "-g3 -O0" which is obviously
bogus.  The error is correct.

It seems like you are confusing a 'make' feature of continuation lines
with the \-newline sequence.  But that's not what you're demonstrating
here, which is shell quoting.

I would actually think that the backslash should be removed by the shell but it
is obviously not what happens. I believe your explanation is correct and
gcc-3.3.6 did not have the check. However, it works with 3.3.6 while not with
newer versions. ;-)

My real problem is https://bugzilla.mozilla.org/show_bug.cgi?id=455468 .

Clues?
