No, only initialization order of the compilation units (cpp files) is
arbitrary, in a single unit the variables are initialized in order as they
appear in the
source. Additionally if you call a function from another unit, this call
initializes all variables preceding this function in the unit before call is
invoked.
This is assured by C++ and (as you probably know) and such function calls are
commonly used to avoid initialization fiasco.
Now back to the fluid: looking into various fluid-generated code, fluid
generates perfectly safe code regarding to such initialization fiasco.
The only problem I can see is that somebody uses or writes
initialization-unsafe internationalization function, but but in such a case
he/she should not enable
internalization in fluid "project settings" in the first place - although I
can not see how somebody would want to use non-safe i18n function, everybody
writes
definitions like
const char * my_string = _("My text");
so the function _() must work before main().
So I do not believe this is fluid problem. I have about 30 internationalized
fluid files, I have looked into generated code (where widgets are constructed
both
as a definition of class and old-fashioned way in a function call) and all code
seems to be safe - I have never encountered initialization fiasco in fltk-1.1.
Is there any STR with a problem description? Otherwise I see no reason not to
allow calling internationalization function during initialization of static
variables (see also my other post).
Menus are very common (not only as Fl_Menu_Bar, but also Fl_Chooice,
Fl_Menu_Button) and Fluid internationalization without it seems quite useless.
I strongly
believe this should go back to fluid (at least as a checkbox option for the
project settings).

PS: Sorry for the rant, but I feel quite frustrated and I do not know what to
do - maybe I will use fluid from 1.1 but I am little bit worried that mixing the
two will bring compatibility problems ;(
