/*

|
* JS private typename definitions.
|
|
*
|
|
* This header is included only in other .h files, for convenience and for
|
|
* simplicity of type naming. The alternative for structures is to use tags,
|
|
* which are named the same as their typedef names (legal in C/C++, and less
|
|
* noisy than suffixing the typedef name with "Struct" or "Str"). Instead,
|
|
* all .h files that include this file may use the same typedef name, whether
|
|
* declaring a pointer to struct type, or defining a member of struct type.
|
|
*
|
|
* A few fundamental scalar types are defined here too. Neither the scalar
|
|
* nor the struct typedefs should change much, therefore the nearly-global
|
|
* make dependency induced by this file should not prove painful.
