[Chicken-hackers] [PATCH] chicken-do: Avoid buffer overrun when preparing Windows command line

[Evan Hanson]

Hello, here's a fix for a bug I encountered while testing Felix's recent
patch on Windows.

The buffer used for the command line executed by chicken-do had size
MAX_PATH, but that's quite short (only 260) so the program would almost
always write beyond it and into the locals passed to CreateProcess(),
causing that call to fail. This patch grows the buffer to the maximum
length handled by CreateProcess() and adds a check for truncation.

Cheers,

Evan
