Actually, I did, in private mails to both you and obrien_at_ few days ago.
I encountered this problem when porting CPP code to FreeBSD recently.
#pragma pack (push/pop) feature is enabled with some major Linux
distributed gcc (Fedora Core is one of them), which increases chances
that we'd have to do something about it, since people tend to write
software, test it under MSVC and Fedora's gcc, see it works there, and
release it.  Current solution of converting #pragma pack (push/pop) to
mere pack(n)/pack() could lead to potential problems (read: bugs) and
just isn't The Right Thing(tm).

Since you asked, I also hope you (or someone else) will upgrade manual
page for gcc, since it's really outdated for -CURRENT at this moment.
If memory serves me right, all necessary patches are in existence, and
probably were submitted to our GCC maintainers already.
