flac dev - May 2011 - 64-bit FLAC structure sizes and padding

Hi all,
As I understand there could be issues to edit/create FLAC files in 64-bit
due to different structure sizes (data alignment and data structure padding
added by 64-bit compilers). I don't know if this have been dealt with before
in this list.

I suggest the following addition to the headers (understood by most
compilers)
#pragma pack(push,4)

FLAC_structures ...

#pragma pack(pop)

That is, retain 32-bit packing of structures even on 64-bit.

But I wonder if this is enough to keep compatibility with FLAC files created
in 32-bit, 64-bit pointers are still 8-bit.

Ideas, anyone?

Cheers Jerker

What makes you thnk there could be issues?

FLAC has been used reliably on 64 bit Linux systems for years. There
is no problem moving FLAC files from 32 bit to 64 bit machines or
moving them the other way. Nor is their any problem moving FLAC
files between big endian and little endian machines.

If you of a problem, please let us know, but don't assume there
is a problem unless you have actually seen one.
