This suggests some problem with the compiler you are using to perform
the build. More than that, I cannot say, because you don't describe
the build environment adequately.

So, the same build system compiler failure as before.

Am I missing something? What exactly are you trying to build? The
above points to Linux platform libraries, which are not what you want
for a Windows cross-native compiler, (nor indeed, for deployment with
a Windows targetting cross-compiler).

OP's original attempt was using mingw-pkg, presumably with the package
specification file I provided in the gcc-5.3.0-mingw32-src tarball;
that specifies --enable-languages=ada (among others), and I'm guessing
that the OP's build compiler isn't ada-aware; it's not even clear if
it is Windows target-aware, (since the build environment hasn't been

Yes. GNAT is a swine to build. I've no idea how the ada folks ever
bootstrap it, because the GCC sources demand a working ada compiler
up-front, at configuration time. I had to begin by bootstrapping a
native Linux build, starting out with an older ada-aware GCC version,
(which was not the default host compiler); that old version was okay
for bootstrapping an updated build, but wasn't good enough to build
the ada libraries, to accompany the Windows-target cross-compiler I
I needed to build next, before I could even begin to configure the
cross-native compiler we now distribute.

Omitting ada from the list specified with --enable-languages should be
all that is required. The OP did that, but it looks like there are
more fundamental problems -- like, the build compiler isn't working!
