Re: RTEMS questions
I've gone through all this C++ in a different O/S, but some of my
experience applies, as it involved gcc.

Note by the way that the C++ [DRAFT] standard does not require any
specific ordering of static initializers in seperate compilation units.
Withing compilation units the constructors are called in order, but
compilation units may be called in any order.
If you need a specific order of initialization, the do_global_ctors()
funtion executes the initializers in order so you can write a linker
script that arranges the .ctor sections of your files in the order you
want them initialized. Not necessarily a general solution.
