This doesn't seem to work on 64-bit. First I get:

configure.c:24: warning: format ‘%i’ expects type ‘int’, but argument 2 has 
type ‘long unsigned int’
...

Replacing %i with %ld in configure.c, this compiles but then I get:

$ make
gcc -ansi -W -Wall -Werror -Wno-long-long -pedantic \
            -c configure.c -o configure.o
gcc configure.o -o configure.exe  && \
        rm -f configure.o
./configure.exe > ocamlsrc/config/m.h  && \
        rm -f configure.exe
ocamlc -c  -I ./ocamlsrc/byterun c_objsize.c
