gcc: VMS Options

1 3.18.54 VMS Options
1 -------------------
1 
1 These '-m' options are defined for the VMS implementations:
1 
1 '-mvms-return-codes'
1      Return VMS condition codes from 'main'.  The default is to return
1      POSIX-style condition (e.g. error) codes.
1 
1 '-mdebug-main=PREFIX'
1      Flag the first routine whose name starts with PREFIX as the main
1      routine for the debugger.
1 
1 '-mmalloc64'
1      Default to 64-bit memory allocation routines.
1 
1 '-mpointer-size=SIZE'
1      Set the default size of pointers.  Possible options for SIZE are
1      '32' or 'short' for 32 bit pointers, '64' or 'long' for 64 bit
1      pointers, and 'no' for supporting only 32 bit pointers.  The later
1      option disables 'pragma pointer_size'.
