Bug#93481: pragma pack works on x86; ignored on arm

[Ben Darnell <bgdarnel@debian.org>]

Package: gcc
Version: 1:2.95.3-7
Severity: normal

Pragma pack works as expected on x86, but is ignored on arm (test case at the
end of this mail, verified on rameau.debian.org).  I understand that pragmas
are deprecated in favor of __attribute__, but this breaks quite a bit of
existing code (see, for example, bug #91911).  I think this should at
least be consistent across all platforms supported by Debian.

Thanks,
-Ben

#pragma pack(2)
struct foo {
	short a;
	long b;
};

int main() {
	/* prints 6 on x86, 8 on arm */
	printf("%d\n", sizeof(struct foo));
	return 0;
};
