incompatible with `stdbool.h`
`stdbool.h` defined `bool` as `_Bool` which nimterop doesn't like, leading to cryptic errors like:
```
Error: unhandled exception: getters.nim(174, 14) `name[0] != '_' and name[^1] != '_'` Identifier 'sapp_touchpoint:_Bool' (nskType) has leading/trailing underscores '_' which Nim does not allow. Use toast flag '--prefix or --suffix' or 'cPlugin()' to modify. [AssertionDefect]
```
the following workaround is possible:
```nim
cPlugin:
  proc onSymbol*(sym: var Symbol) {.exportc, dynlib.} =
    if sym.name == "_Bool": sym.name = "bool"
```
but it would be nice if nimterop was able to detect cases like this. if that's not a goal i guess maybe this could be added to wiki as a pitfall in case anyone else encounters this problem in the future.
