Re: [P21.5] Patches for Native Windows Builds

Here are the patches necessary to build on Windows native, using VS6. Please note a couple of things: 1) no attempt is made to support TLS. This is the patch necessary to go on building w/o TLS. 2) I don't understand why the patch to sysdep.c is necessary, but without this, the call to ioctl yields an "undefined identifier" from VS6. The only changes made to sysdep.c between 21.5.34 (which doesn't need this commenting out) and now were hygenic changes made by Aidan. Something must have changed in a header file, but I don't know what.
