Hi,

Cygnus's newlib has a bug in execvp():
it handles relative path names incorrectly.
Specifically, it searches the PATH (only) even
for filenames that include `/', such as `./foo'.
If your PATH does not include ".", then gnu-win32's execvp()
will fail on such cases.

	main() {
		char *argv[] = { "./foo", 0 };
		execvp(argv[0], argv);
	}

This bug causes `make' in gnu-win32 to fail when executing
commands such as `./foo' if PATH does not include ".".
