-output-obj).
val mkdll : string
The linker command line to build dynamic libraries.
val mkexe : string
The linker command line to build executables.
val mkmaindll : string
The linker command line to build main programs as dlls.

val max_tag : int
Biggest tag that can be stored in the header of a regular block.
val lazy_tag : int
Normally the same as Obj.lazy_tag. Separate definition because of technical reasons for
bootstrapping.
