of conglomerated newargv.setup(). Let newargv.setup() decide when to call dup_all(). Only set argc and argv for cygwin processes. (av::setup): Rename from av::fixup. Accept argc and argv parameters. Fill out argv and argc here. Duplicate whole argv structure when this is a Cygwin executable. * winf.cc (linebuf::fromargv): Don't bother duplicating argv elements since they will never be used. * winf.h (av::set): Delete. (av::setup): Rename from av::fixup. Add two parameters. (av::replace0_maybe): Assign calloced to 1 rather than 'true' for clarity. (av::dup_maybe): Delete. (av::dup_all): Set calloced to show that we have duplicated all of the arguments in the list.

bigger than this value, the stack position is suddenly moved up by 64K for

no apparent reason, which results in subsequent forks failing. Since Cygwin
