gcc: Darwin Pragmas

1 6.61.7 Darwin Pragmas
1 ---------------------
1
1 The following pragmas are available for all architectures running the
1 Darwin operating system. These are useful for compatibility with other
1 Mac OS compilers.
1
1 'mark TOKENS...'
1 This pragma is accepted, but has no effect.
1
1 'options align=ALIGNMENT'
1 This pragma sets the alignment of fields in structures. The values
1 of ALIGNMENT may be 'mac68k', to emulate m68k alignment, or
1 'power', to emulate PowerPC alignment. Uses of this pragma nest
1 properly; to restore the previous setting, use 'reset' for the
1 ALIGNMENT.
1
1 'segment TOKENS...'
1 This pragma is accepted, but has no effect.
1
1 'unused (VAR [, VAR]...)'
1 This pragma declares variables to be possibly unused. GCC does not
1 produce warnings for the listed variables. The effect is similar
1 to that of the 'unused' attribute, except that this pragma may
1 appear anywhere within the variables' scopes.
