A perfect opportunity, you can now use SAS/C instead!  Seriously, it
sounds to me like you haven't tried the compiler environment in the 
last couple of years.  It's changed a tremendous amount.  Come 
see it in the booth at an AmiExpo sometime.

Or do this:

#define DCL(name, type) char c_##name[sizeof(type)+3];\
                        type * name = (type *)((((long)c_##name+3)>>2)<<2);

DCL(fib, struct FileInfoBlock);

Then fib will automagically be initialized to point to an aligned
FileInfoBlock.  This works for autos, statics or externs, as long
as the compiler you are using supports ANSI token pasting (##) which
I know SAS/C does and I'm pretty sure Manx does.
