Mechanically change INT to FIXNUM in our sources.
src/ChangeLog addition:
2011-10-09 Aidan Kehoe <kehoea@parhasard.net>
[...]
Mechanically change INT (where it refers to non-bignum Lisp
integers) to FIXNUM in our sources. Done for the following
functions, enums, and macros: Lisp_Type_Int_Even,
Lisp_Type_Int_Odd, INT_GCBITS, INT_VALBITS, make_int(), INTP(),
XINT(), CHECK_INT(), XREALINT(), INT_PLUS(), INT_MINUS(),
EMACS_INT_MAX (to MOST_POSITIVE_FIXNUM), EMACS_INT_MIN (to
MOST_NEGATIVE_FIXNUM), NUMBER_FITS_IN_AN_EMACS_INT() to
NUMBER_FITS_IN_A_FIXNUM(), XFLOATINT, XCHAR_OR_INT, INT_OR_FLOAT.
The EMACS_INT typedef was not changed, it does not describe
non-bignum Lisp integers.
Script that did the change available in
http://mid.gmane.org/20067.17650.181273.12014@parhasard.net .
modules/ChangeLog addition:

[...]
Mechanically change INT to FIXNUM, where the usage describes non-bignum
Lisp integers. See the src/ChangeLog entry for more details.

Lisp integers.
