0.6.5 compilation problem with gcc 4.0.3

gcc -c -DHAVE_CONFIG_H -I./c -I./cig  -O -march=i386 -pipe -DPIC -fPIC
-O2 -o c/unix/io.o c/unix/io.c
c/unix/io.c: In function 'ps_write_integer':
c/unix/io.c:154: error: invalid storage class for function 'write_integer'
c/unix/io.c: At top level:
c/unix/io.c:171: error: conflicting types for 'write_integer'
c/unix/io.c:160: error: previous implicit declaration of
'write_integer' was here
make: *** [c/unix/io.o] Error 1

   149	long
   150	ps_write_integer(long n, FILE *port)
   151	{
   152	  int status;
   153	
   154	  static long write_integer(unsigned long n, FILE *port);
   155	
   156	  if (n == 0) {
   157	    WRITE_CHAR('0', port, status);
   158	    return status; }
   159	  else if (n > 0)

 I moved the write_integer prototype outside the ps_write_integer
function body and it went and compile happily. Best guess is that gcc
is misinterpreting the intent of the static keyword in this context as
a persistant variable instead of a symbol local to the compilation
unit?
