I'm using dir.h in an ancient program written circa 1999 and the program uses #pragma pack(1) with the comment /* Kill pragmas from dir.h */. Where is pragma pack(0) documented?

This whole pragma business is=20= for GCC 2.7.2 and below, so one
possible solution is to condition the pragmas on those versions.

Alternatively, we could use "#pragma pack(0)", as this is documented
to reset the packing to the default, but I'm afraid that old versions
of GCC might not support that (otherwise, why didn't we use pack(0) in
the first place?).

Comments?

Where is pragma pack(0) documented?
