C-u M-%

You can replace by using a regular expression -- use `C-M-%'. 

"\<" matches the beginning of a word, and "\>" matches the end of a
word.  So "\<int\>" is the string you want to search for.

hee hee answer:

     #define int double

sometimes i wish there were a C-M-% for days of the week...

You could alternatively M-% " int " RET " double " RET !  [no quotes]
(or maybe M-% "(int " RET "(double " RET !) though this in't the elegant
way.

If I were you I would do it the way Jesper suggests, but I would
replace it with another term, say num_type.  Then put at the top
something like ttn suggests :-

#define  num_type int;
/* #define num_type double; */

(Or use typedef.)

This allows you to change things easily.  I've often done this in the
past to allow me to experiment with using doubles and floats.
