I don't know about false positives, but adding -Wconversion certainly
adds enough warnings of the type:

dispnew.c:6060: warning: conversion to 'int' from 'Lisp_Object' may alter its value
dispnew.c:6106: warning: conversion to 'int' from 'long int' may alter its value
dispnew.c:6421: warning: conversion to 'int' from 'long int' may alter its value
dispnew.c:6422: warning: conversion to 'int' from 'long int' may alter its value
dispnew.c:6424: warning: conversion to 'long unsigned int' from 'int' may change the sign of the result
dispnew.c:6424: warning: conversion to 'unsigned int' from 'long unsigned int' may alter its value
...

[larsi@quimbies ~/src/emacs/trunk/src]$ make 2>&1 | grep warning | wc -l
7152

Somebody has a lot of work to do.  :-)

(Or not.)
