I understand the problem. When building MiNT software, setting a correct 
stack size is an absolute requirement. And the standard makefiles are not 
aware of that. I guess this is especially a problem for Gentoo, where 
standard source packages should be downloaded and compiled transparently.

However, I don't know the best way to do that. Certainly, as you proposed in 
your other message, a specific environment variable used by the linker would 
be simple and efficient. But it would be very nonstandard. Maybe the 
binutils has some way to provide default options, I don't know.
Or maybe Gentoo is flexible enough to customize makefiles ?
Or maybe configure, with something like the file config.site ?

My feeling is that we should see how this kind of problem is solved on other 
platforms before adding a new functionality inside the linker.

Oh, I didn't notice, but both syntaxes work.
In the --help message, I have used the same syntax as the --stack option 
specific to the Win32 linker, described in "man ld".

So I think it is correct like this (but the usage of = should be consistent 
among all options).
