I though that this might be important enough to share on the announce list:

A pull request [1] by Rainer Schuetze which adds COFF support for Win32 has recently been merged by Walter. It seems to be enabled using the -m32mscoff flag.

Wow, that's fantastic news! Thank you very much Rainer!

I have just recompiled dmd, but I don't see that new compiler
switch (dmd 2.067).

I am compiling in a wrong way?

are you sure that you compiled dmd for 32-bit windows? other versions seems to not have this flag.

Yes, I am using a 32 bit Windows.

are you sure that you have latest git then? yes, i know that this is very silly question, but sometimes... ;-)

unfortunately, i have no windows boxes (neither cross-compilers), so can't check it myself. but i see this in mars.c:

#if TARGET_WINDOS
            else if (strcmp(p + 1, "m32mscoff") == 0)
            {
                global.params.is64bit = 0;
                global.params.mscoff = true;
            }
#endif

...

static const char* parse_arch(size_t argc, const char** argv, const
char* arch) {
    for (size_t i = 0; i < argc; ++i)
    {   const char* p = argv[i];
        if (p[0] == '-')
        {
            if (strcmp(p + 1, "m32") == 0 || strcmp(p + 1, "m32mscoff")
== 0 || strcmp(p + 1, "m64") == 0) arch = p + 2;
            else if (strcmp(p + 1, "run") == 0)
                break;
        }
    }
    return arch;
}

so i believe that it should work.

OK, -m32mscoff works (probably I was using a wrongly written switch), but I don't see it listed among the other compiler switches.

maybe this is due to mscoff support still considering 'experimental'?

You will need to use his unmerged branches of druntime and phobos also:

https://github.com/rainers/druntime/tree/coff32
https://github.com/rainers/phobos/tree/coff32

Hopefully those get merged next, as I think this could be a big feature for the 2.067 release.  Nice work, Rainer.
