Issue at compilation
Dear ocamlcc developers,
I just installed ocamlcc with OPAM, and tried to compile a bytecode program. But I got the following error:
ld: unknown option: -E
collect2: ld returned 1 exit status
Error: command '/usr/bin/gcc -D_FILE_OFFSET_BITS=64 /var/folders/d3/bn5myb2950n5q31dc87xt9dm0000gn/T/tmp-ocamlcc-bdaef2.c -o fib.out -I /Users/john/.opam/system/include/ocamlcc -I /Users/john/.opam/system/include/ocamlcc/ocamlcc-byterun-4.00 -lm -ldl -lcurses -Wl,-E -O3 -Wall' failed.
I'm using MacOS X 10.8 with OCaml 4.00.1. Everything works fine if I manually compile the generated C file without the option -Wl,-E.
ocamlcc: link error with Unix module
If I use the Unix module then ocamlcc fails to link (even if I used -custom to generate the bytecode), and I have to manually add to -ccopts to make it link.
Testcase:
$ cat >x.ml <<EOF
let () =
Printf.printf "Time: %f\n" (Unix.gettimeofday ())
EOF

$ ocamlcc -verbose x.byte
