Summary: inconsistent -Wl,option paths handling

Initial Comment:
Situation, under MSYS, running bash:

$ pwd
/tmp
$ mount | grep tmp
T:\Temp on /tmp type user (binmode,noumount)
$ cat v.c
extern void foo();
$ ls -l /t/Temp/vs
-rw-r--r--    1 zeitlin  Administ       38 Nov  9 11:49
/t/Temp/vs
$ cat vs
V_1_0 {
    global:
        *;
};

Problem:

$ g++ -shared -o v.dll v.c -Wl,--version-script,/t/Temp/vs
d:\mingw32\3.4.2-20040916\bin\..\lib\gcc\mingw32\3.4.2\..\..\..\..\mingw32\bin\ld.exe:
cannot open l
inker script file /t/Temp/vs: No such file or directory
collect2: ld returned 1 exit status

And -Wl,--version-script,/tmp/vs gives the same error.


But all of these commands work as expected:

$ g++ -shared -o v.dll v.c -Wl,--version-script,vs
$ g++ -shared -o v.dll v.c -Wl,--version-script,t:/Temp/vs
$ g++ -shared -o v.dll v.c -Wl,--version-script=/tmp/vs
$ g++ -shared -o v.dll v.c -Wl,--version-script,/t/Temp/vs


IOW, everything works ok if -Wl,--version-script= is
used but if comma is used instead of '=' then only the
paths not starting with slash (or backslash) work. This
is pretty weird and while the workaround is obvious
once you know it and version script is useless under
Win32 anyhow (but is still used by packages using
configure to detect ld version-script option support --
why does mingw32 ld support it at all?), it still was
not obvious to fix and it would be nice if it could
work or at least fail with some intelligible error
message. Thanks!

Do we really want to do this?  How do we handle the heuristics to decide
when to and when not to?

I'll need to take a look at the coding but I think at the moment my stance
will be that you *must* use the work around.  I don't remember if I took
care of this in the 1.0.11 update.  It certainly is low on the round tuit
list.

I'm updating this bug because it turns out that exactly the
same problem affects -Wl,--out-implib (works with '=' but
not with ',') and this is much more serious as it can't be
just avoided, unlike -Wl,--version-script.
