Ticket details:
The Ada component for GCC-10 has introduced a gratuitous dependency on
Microsoft's <versionhelpers.h> API. Notwithstanding that this is an appalling
choice, by the GCC-Ada developers — OS version, (which is what this API tests,)
is never a reliable indicator of feature availability — to facilitate
continuing support for GCC-Ada, in MinGW, it is almost imperative that we
provide our own <versionhelpers.h> API emulation; (the alternative would be to
commit to patching future versions of GCC-Ada, in perpetuity, to circumvent
this ill-advised dependency).

Comment:
Microsoft first introduced the <versionhelpers.h> API as a component of the
Windows 8.1 Software Development Kit. However, as noted in Microsoft's
documentation, this API is based on the VerifyVersionInfo() function, which,
according to the pertinent documentation, has been supported on all WinNT
derivatives since Windows 2000, and thus, the <versionhelpers.h> API is
backwardly compatible with Win2K, and all subsequent WinNT derivatives.
Unfortunately, while backward compatibility with Win2K, and all later WinNT
derivatives, may be sufficient for many applications, it does not satisfy
MinGW's objective of supporting even earlier WinNT variants, and Win9x;
(indeed, the MinGW libraries are compiled with nominal support for WinNT4, with
additional compatibility infrastructure to support Win9x). Any MinGW emulation
would, thus, need to incorporate such "legacy-support" infrastructure, even if
such support offered no more than an indication that the run-time platform is
too old for the requested level of support; (indeed, such an indication would
be entirely appropriate, since the API specification incorporates no test for
any OS version prior to IsWindowsXPOrGreater()).
