I will be adding some form of #pragma pack to our C/C++ compiler on
most platforms to support the inclusion of third party headerfiles
that assume that the structures are packed. The open question, is how
best to achieve that. I tried HANDLE_SYSV_PRAGMA but that logic fails
to work, in fact, I don't see how most ports could make use of the
code in c-pragma.c. Is there a port that someone can say does
currently work with that scheme? My preference is to reuse the most
popular existing scheme. Should I just blaze away and fix up c-pragma
to work as expected? What is expected?
Also, does egcs want these types changes when I am done with them, or
do you prefer that the not go into the egcs distribution?
Please, I know and understand all the arguments against using #p
anything... don't need to repeat those now.

HANDLE_PRAGMA is due for overhaul, so that it can work together with
USE_CPPLIB. Its set of arguments will have to be changed. This
requires changes in the backend as well as in all ports that use
HANDLE_PRAGMA. I suggest you do that first; when you have done that,
it should be easier to use the code in c-pragma.c, since HANDLE_PRAGMA
should be passed a (not necessarily proper) superset of parameters,
when compared to HANDLE_SYSV_PRAGMA.

Ah, never mind, pilot error, it works as expected, sorry about that...
I'll just do up a patch to use the existing scheme.
