conflicting types for `__malloc_hook'

I am trying CVS version from August 8th, 2001

I had the same Problem with fnccheck-1.4

gcc -Wall -O3 -fPIC -DFNCCHK_USE_THREAD
-I/usr/local/include -I/usr/include -c fnclibmalloc.c
fnclibmalloc.c:81: conflicting types for
`__malloc_hook'
/usr/include/malloc.h:226: previous declaration of
`__malloc_hook'
fnclibmalloc.c:82: conflicting types for
`__realloc_hook'
/usr/include/malloc.h:229: previous declaration of
`__realloc_hook'
fnclibmalloc.c:83: conflicting types for `__free_hook'
/usr/include/malloc.h:224: previous declaration of
`__free_hook'
fnclibmalloc.c:84: conflicting types for
`__memalign_hook'
/usr/include/malloc.h:232: previous declaration of
`__memalign_hook'
make[2]: *** [fnclibmalloc.o] Error 1
make[2]: Leaving directory `/usr/src/fnccheck/src/lib'

Quick fix:

remove definitions in fnclibmalloc.c line 81 - 84

My System:

Debian Woody
