[Daniel Green]

Please post all issues in D.gnu or on GDC's site 
https://bitbucket.org/goshawk/gdc

Due to the use of a newer runtime than TDM64-GCC it is **recommended** 
to install a copy specifically for GDC.

Features
  **ALPHA** As in, D2.058 support is still new.
  * D2.058
  * Debug information available using gnu-debuglink.
  * Removed D1(Did anyone use this featuer?).
    * Due to current system breaking with repository changes and D1
      being discontinued at the end of the year.
  * binutils with TLS patches
  * mingw-w64-runtime with TLS and stdio fixes.
  * GCC 4.6.1 with TLS patches

Installation instructions:

1. Download and install TDM MinGW64
2. Extract the downloaded archive into the base of the newly installed 
TDM install.

If you've done this before, you can just do step 2.
