very simple "which" alternative for Windows

which.c

#include <stdio.h>
#include <windows.h>

int main(int argc, char **argv)
{
	if (argc == 2)
	{
		char path[MAX_PATH];
		HINSTANCE ret = FindExecutable(argv[1], 0, path);
		if ((int)ret > 32)
			puts(path);
		else
		{
			fprintf(stderr, "WHICH: cannot found %s (FindExecutable returned %d)\n", argv[1], ret);
			return 1;
		}
	}
	else
	{
		printf("Finds first or all executables on path, or which executable is associated with a document file or extension.\n\nWHICH command\n\n    command - Command name.\n");
	}
}
