Precompiled GDC binary issues

[Daniel Green]

Are you using the 64-bit version of TDM?  This usually gets installed 
into c:\MinGW64 but you mention that you copied the files into 
c:\MinGW32 .

The error can also indicate that the DLL is missing exported functions 
required by the executable.

I've encountered the same error when mixing the binaries and DLL files 
from TDM32 and TDM64 versions.

I can also produce the same error by attempting to run GDB from TDM32 
with TDM64 DLLs on the path.
