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'.
