PORTABILITY
POSIX.2. x/OPEN Portability Guide 4.0. Windows Me. Windows NT 4.0. Windows 2000. Windows
XP. Windows Server 2003. All UNIX systems.
On Windows systems, the archive format is either OMF, or the Common Object File Format
(COFF). The options included in this implementation are the best possible approximation of those
defined by the POSIX standard for the ar command, to make makefiles reasonably portable. For
historical compatibility, you can omit the - preceding the options if the options appear only as the
first argument after the command name.
