I'm having problems with a redefinition of PARAMS on some FreeBSD
systems. These system uses the libintl.h that's generated from
../intl/intlh.inst.in, which provides a definition of PARAMS if it
isn't already defined. This libintl.h is included from gdb_locale.h.
Since our ansidecl.h header defines PARAMS unconditionally, and is
included *after* gdb_locale.h in defs.h, this results in a compiler
warning, and since I tend to use -Werror, this leads to a failure.
Yes, getting PARAMS defined (i.e., including "ansidecl.h") as early as
possible ``feels safer''.
