* 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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@158908 138bc75d-0d04-0410-961f-82ee72b054a4
