As no better ideas turned up until now, truncwarn appears to be of limitied use
as it only seems to warn when truncating from 64bit to <64bit (and not, e.g.,
when truncating from 32bit to 16bit; at least with CC 5.5), and most other
truncations (at least in not Unix-only code) will be caught by the Microsoft
Windows compiler, I would say we should disable truncwarn globally in
solenv/inc/unxsols4.mk:1.25 and solenv/inc/unxsoli4.mk:1.17, see patch below.
Pavel, can you do that on pj55? Thanks.
