Portability

[simonlindholm]

Librcd currently only supports x86_64 Linux. Porting to other platforms (esp. Windows) would be a large undertaking and probably break some abstractions, and is not at the moment planned. Still, opening this as a tracking issue.

The following things are Linux-specific:

• Low-level code, such as lwthreads, signal handling and the code for segmented stacks (all .s files).
• I/O (files, pipes, network, executing programs, etc.)
• The musl libc compatibility layer.
• Backtraces depend on details of ELF (reflect.c).

64-bit specific:

• all assembly code
• memory allocation?
• integer types?

Clang would need certainly patching also. (@hannes-landeholm, plz edit this comment and add some details)
