The main problem is that these toolchains use some GCC patches. These
need to be ported to newer GCC releases. This is usually the only
problem.

I'm not sure if the PSP toolchain is still supported. It seems like the
sources weren't modified in the last 4 years. All other PSP
buildscripts seem to use the same GCC 4.6 patches, so there's not much
we can do.

You could probably ask for some more information in the devkitPro forum.

There's some very basic information here:
http://wiki.dlang.org/GDC/Installation/Generic#Building_only_Druntime.2FPhobos
Only tested on linux though. It should work on windows if you use a
msys2 installation and install the base-devel package.

Note that you need the GCC sources as well (unpatched is OK). These
won't be compiled but the druntime Makefile/configure scripts depend
on some macros from these sources.

It might be clever to use the same druntime and GCC sources that were
used when building these compilers. This means GCC4.8 + gdc-4.8 branch
for devkitPPC and GCC4.9 + gdc-4.9 branch for devkitARM.

(I'm not sure if you have to pass some additional devkitPro specifc
flags to GCC? If think these could be set using the LDFLAGS/DFLAGS
environment variable, but I'm not sure)
