[Freeciv-Dev] compile errors on bitvector code with Sun cc (PR#2046)

[Reinier Post <rp@xxxxxxxxxx>]

  Dear Per,

The Sep 10 snapshot fails to compile with with Sun's (ANSI) cc:

cc -DHAVE_CONFIG_H -I. -I. -I.. -I./../common -I./../server -I../intl    -g -c 
`test -f advattitude.c || echo './'`advattitude.c

The lines in unittype.h invoke the BV_DEFINE macro; I have no idea what goes
wrong there.  The problem in aitools.h is a define that contains "..." in the
argument list, which is not a construct I can find anywhere.
