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

	2 large exe/dlls via Visual Studio.

	3

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

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

	6

	7 ...RSP00002E45885644.rsp : fatal error LNK1170: line in command file contains 13 1071 or more characters

	8

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

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

	11 one line which is what the IDE generates.

	12

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

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

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

	17 and make sure to run vsvars32.bat first.
