Nimrod supports these `calling conventions`:idx:\:
`nimcall`:idx:
is the default convention used for a Nimrod **proc**. It is the
same as ``fastcall``, but only for C compilers that support ``fastcall``.
`closure`:idx:
is the default calling convention for a **procedural type** that lacks
any pragma annotations. It indicates that the procedure has a hidden
implicit parameter (an *environment*). Proc vars that have the calling
convention ``closure`` take up two machine words: One for the proc pointer
and another one for the pointer to implicitely passed environment.
`stdcall`:idx:
This the stdcall convention as specified by Microsoft. The generated C
procedure is declared with the ``__stdcall`` keyword.

Fastcall means different things to different C compilers. One gets whatever
the C ``__fastcall`` means.

The syscall convention is the same as ``__syscall`` in C. It is used for
interrupts.
