Mac 10.4 compile with gcc 4.0: flip.c error

[Marshall DeBerry]

I'm getting the following when compiling under Tiger (10.4) with gcc 4.0:


flip.c: In function 'cmd_flip':
flip.c:106: warning: passing argument 3 of 'dict_get_vars' from incompatible
pointer type
flip.c: In function 'flip_sink_create':
flip.c:288: warning: pointer targets in passing argument 1 of
'st_bare_pad_copy' differ in signedness
flip.c: In function 'flip_file':
flip.c:433: error: 'off_t' undeclared (first use in this function)
flip.c:433: error: (Each undeclared identifier is reported only once
flip.c:433: error: for each function it appears in.)
flip.c:433: error: parse error before "i"
make[3]: *** [flip.o] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

Didn't this "off_t" issue appear before when doing a compile on the Mac?
