Here is a list of warnings that I get while compiling php3,
reformatted a bit for ease of reading. (It compiles and runs
fine.)

Configure line is:
./configure --with-mysql=/mySql --enable-safe-mode
--enable-track-vars --enable-debugger --prefix=/www1
--enable-bcmath "--bindir=\${exec_prefix}"
--enable-maintainer-mode --with-config-file-path=/www1                           

Replace GCC with:

gcc -O2 -I. -I/mySql/include -g -Wall -Wmissing-prototypes
    -Wstrict-prototypes -Wmissing-declarations


GCC -c language-parser.tab.c -o language-parser.tab.o

Most of these fixed, some new ones, here is the current set
to document them:

debugger.c:478: warning: no previous prototype for
     `_php3_send_error'
functions/file.c:174: warning: no previous prototype for
     `php3_closesocket'
functions/math.c:461: warning: no previous prototype for
     `_php3_number_format'


---

I don't think we should have -Wmissing-prototypes generated
warnings on the bug database.  They are harmless in 99.99%
of the cases, no point at showing them off.
Generally, every once in a while somebody can turn on
-Wmissing-prototypes and fix all of these warnings up.
