+ * collect2.c (vflag): Change type from int to bool.
+ (debug): Likewise.
+ (helpflag): New global bool.
+ (main): Set vflag and debug with boolean, not integer truth
+ values. Accept new "--help" option and output usage text if
+ found.
+ * collect2.h (vflag): Update prototype.
+ (debug): Likewise.
