I was asking about whether or not OCaml has the ability to target specific integer size and signedness, as F# does. I would like to construct precise software that targets the specific kinds of ints that compilers have historically facilitated microprocessors to process, but using a functional language instead of C or C++.

The F# folks (including Don Syme) did a fantastic job on the early versions of the language (I used it up to ver 2 or early 3), but I am tired of the corporate engine that funds that ecosystem. I now construct my software within an operating system of a different pedigree. Such considerations are important to me, but thanks for sharing your preference. As for me, I hate nothing or no one, but I am as picky as a poor man can be about whom I choose to rely on for my tools.

As for your opinion on the borderlands of mental illness, I'll contact you at your outlook email address should I seek your opinion about such differently-technical topics. But I was only asking if the OCaml compiler can target specific varieties of ints, as the .NET compiler does.
