I have GNAT 5.03a, Windows XP.

This appears to be a library version problem. 'CryptProtectData'
doesn't appear to be in lib/gcc/pentium-mingw32msv/3.4.4/libcrypt32.a,
nor in any other library file in that directory.

However, 'CryptProtectData' is in Windows/system32/crypt32.dll.

So I suggest you use one of the dll tools to recreate libcrypt32.a
from Windows/system32/crypt32.dll, and see if that works. If it does,
send a bug report to AdaCore.
