After my 1st round of fixes I get:
76 unused variable
198 was hidden
8 usually a function
5 no effect
15 for conversion from
15 because conversion sequ
122 bracketed initializer
30 previous definition
30 defined but not used
2 is not used
32 comparison between signed and unsigned
6 large integer implicitly truncated to unsigned type
8 not handled in switch
3 overflow in implicit constant conversion
61 misc (other than the above)
There are no longer any "prototype" or "implicit declaration" warnings.
I did these first since "fixing" type warnings before fixing the
prototype/declaration warnings can actually introduce bugs.
The only "pointer" warnings left are 70 in /js/
57 "cast from pointer to integer"
13 "cast to pointer from integer"

I've been using:
/usr/bin/gcc -Wmissing-declarations -Wmissing-prototypes -Wstrict-prototypes
-Wpointer-arith -Wuninitialized -Wimplicit -Wreturn-type -Wformat
-D__STDC__=1 -Dunix $@
(and the same for g++)
This really would take forever with Werror. I fixed hundreds of prototype/declaration
warnings between compiles.

No, I started with the firefox-1.0 tar file from mozilla.org.
