+Linker shim that enables the use of "Use Library Dependency Inputs" on

+large exe/dlls via Visual Studio.

+That flag is required to enable useful incremental linking, however, with a

+large number of objects in components, the linker fails with:

+...RSP00002E45885644.rsp : fatal error LNK1170: line in command file contains 131071 or more characters

+This seems to be that the IDE team didn't talk to the linker team; the

+response file can handle long commands, just all the files can't be on

+*one* line which is what the IDE generates.

+So, this program simply replaces link.exe, fixes the response file, and

+then shells to the original linker. Ridiculous? Yes. Faster links? Yes.

+Compile/install with install_supalink.py. Run from cmd.exe as Administrator,

+and make sure to run vsvars32.bat first.
