[Scummvm-devel] START_PACK_STRUCTS default changed -- port breakage

[Max Horn]

Hi folks,

since I never got any complaints regarding my proposed  
START_PACK_STRUCTS changes either, I implemented those now, too.

Now, START_PACK_STRUCTS / END_PACK_STRUCTS always default to doing  
#pragma pack push/pop, which should work on GCC, MSVC, Metrowerks  
CodeWarrior and others. I.e. scummsys.h now says:

#ifndef START_PACK_STRUCTS
#define START_PACK_STRUCTS pack(push, 1)
#define END_PACK_STRUCTS   pack(pop)
#endif


A few ports may be broken by this change now. Affected porters can  
restore their port by simply adding appropriate (possibly empty)  
#define's for their port, e.g.

#define START_PACK_STRUCTS
#define END_PACK_STRUCTS


My next change will be to remove GCC_PACK (assuming my testings for  
that turn up positive).


Cheers,
Max
