Hi
on my i486-unknown-elf target i am unable to use #pragma pack(push[,n]) /
#pragma pop(n), which happen to be the same as Microsofts #pragma syntax.
this is because HANDLE_PRAGMA_PACK_PUSH_POP is only defined for
linux/i386/alpha/sparc freebsd and others.
Is this correct ?, comments in the appropreate config.h files indicate that
HANDLE_PRAGMA_PACK_PUSH_POP, is mostly used for wine compatablity, but is
there any reason why HANDLE_PRAGMA_PACK_PUSH_POP is not present on all
targets ? also there is not a configure option.
i note that in gcc4 only djgpp and cygming targets have
HANDLE_PRAGMA_PACK_PUSH_POP defined, also the gcc4 documentation does not say
these #pragmas are target spesific.
regards
