annotate lib-src/make-dump-id.c @ 5582:873d7425c1ad
Change integer to fixnum in a few places where it wasn't possible mechanically.
src/ChangeLog addition:
2011-10-09 Aidan Kehoe <kehoea@parhasard.net>
Do a couple of non-mechanical things that would otherwise have
been included in the last change.
* data.c:
* data.c (Ftype_of):
Return Qfixnum for fixnums, not Qinteger.
* lisp.h (MOST_POSITIVE_FIXNUM):
Delete an obsolete comment here.
man/ChangeLog addition:
2011-10-09 Aidan Kehoe <kehoea@parhasard.net>

* internals/internals.texi (Modules for Other Aspects of the Lisp Interpreter and Object System):

Say fixnum rather than integer when specifically talking about
fixed-width Lisp integers.
