[linuxsh-dev] #pragma pack

[Bryan R. <br...@ix...>]

Hi,

I've been working on building the latest CVS kernel using the older
toolchain and gnb's patch:
http://sourceforge.net/patch/download.php?id=103106

and I keep getting lots of these:

---

I've run into the same warning when porting some of our in-house code...
does the old toolchain not implement #pragma pack? If not, why not, and
will the new one?

In the meantime, I've applied my following patch (hack?):

--- udf_fs_sb-old.h     Thu Jan  4 21:57:34 2001
