# If primitives contain duplicated lines (e.g. because the code is defined

# #ifdef X
# CAMLprim value caml_foo() ...
# #else
# CAMLprim value caml_foo() ...
# end), horrible things will happen (duplicated entries in Runtimedef ->
# double registration in Symtable -> empty entry in the PRIM table ->
# the bytecode interpreter is confused).
# We sort the primitive file and remove duplicates to avoid this problem.

# Warning: we use "sort | uniq" instead of "sort -u" because in the MSVC
# port, the "sort" program in the path is Microsoft's and not cygwin's
