I'd need to know what undefined reference errors there were and what the simple program was. ;)

No program seems immune :-)  But try this:

///////////////////////////////////
import std.stdio;

void main()
{
    writeln("Hello, gdmd!");
}
///////////////////////////////////

... which compiled with gdc proper works fine, but when compiled with gdmd results in this:

OK, it's a driver bug. Reproduced using:

gdc -c hello.d
gdc hello.o

Luckily for you the driver is separate from the compiler proper, so you don't need to recompile the entire gcc sources. ;)

Aaack, I should have thought to try that before assuming it was gdmd.  I'd forgotten that gdmd technically builds the object file first and then compiles to the executable.

Thanks very much for the fix! :-)

I should add that this is the first time I've successfully compiled GDC with the --enable-multiarch option.  Did something change recently?

Nope. Though I thought that debian patches were still needed in order to be compatible with Debian/Ubuntu's multiarch directory structure.

I'm fairly sure I remember you telling me that Debian patches weren't needed for GCC 4.8 and later, although with 4.8-based builds with --enable-multiarch would fall over.

Just rechecked, gdc-multiarch patch is commented out in rules.patch. ;-)

Anything in particular I could try out to see if it's working in practice?
