This option only afects bitfield structures. None of the few structures that are
mapped directly within GtkAda are concerned.

Note that this is an interesting area where the design decision made to
avoid mapping the underlying C structure (and use pointers instead) has
proven very useul: it provides a much better compatbility among versions and
avoid problems such as this one.

We do not use configure. The C files (e.g misc.c) are built manually and put
in a DLL (gtkada-xxx.dll). The GtkAda files are built using gnatmake make
