# C does in fact support octal literals, marking them as starting with an
# unnecessary initial zero. This is practically obsolete now, and in any case
# makes no difference to syntax-colouring. Binary literals were in theory
# rejected by the C standards body as useless, but are so useful that gcc
# and clang support them anyway.

Binary Literal Prefix: "0b"

# The "shebang" routine for a language is called to add anything it wants to
# at the very top of the tangled code. (For a scripting language such as
# Perl or Python, that might be a shebang: "hence the name.)"
# But we will use it to defime the constant PLATFORM_POSIX everywhere except
# Windows. This needs to happen right at the top, because the "very early
# code" in a tangle may contain material conditional on whether it is defined.

Shebang: "#ifndef PLATFORM_WINDOWS\n#define PLATFORM_POSIX\n#endif\n"
