But I need more than that. There are platform issues with NaN, infinity
constants and their handling. Also many differences in curses. 

Solaris adds grief for C types of attributes and the lack of/difference 
in certain attribute functions. I also need to know whether you can 
customize the colour palette in a given implementation of curses (and 
pdcurses). Include files vary by platform for some of the C routines, 
which will be called by the Ada code. Whether or not I have alloca() 
support is another important configuration item.

Add to that release to release changes in 3rd party support like libgsl,
libgmp and PostgreSQL and you'll find a strong need for extensive 
configuration control. So autocrap does control all that for me, along 
with a few hand-crafted platform tests where it falls short.
