I am just fixing the code in GNAT for interfacing with C wide characters.
GNAT assumed that C wchar_t was a 16-bit quantity, but we were notified
by a user that this actually was defined as Integer'Size in GCC. If this
definition may be changed to 16-bit anytime soon, I'd like to know so
I can avoid double changes.

It seems strange to me that there is no system ABI specifying this exactly...
What do the different Unices expect in their system calls?
