- Is anyone using GCC 2.3.1 and getting *correct* behavior
- on a 386BSD system or other NET 2 system?
-
- I was sent a description of how those systems try to work,
- and thought I had fixed 2.3 to work with them.
- Now I'm told that NET 2 does not use _VA_LIST_ the way the
- comments in ansi.h say it should be used, and that this
- version of gvarargs.h should be used instead.
-
- IF you get this message before noon on Friday Nov 7,
- or if you are a real expert on NET 2 systems,
- please tell me whether 2.3.1 works for you, and whether
- this modified gvarargs.h works for you.
