- use `const char*` for string literals
- do not use `NULL` as integer
- use `/` as path separator
- do not hard-code platforms

Visual Studio is notoriously lax with these rules.

- add `template`/`typename` where necessary
- fix template constructor call
- declare template before use
- declare explicit instantiations `inline`
- `typedef`s are not allowed in destructor declarations

- `__debugbreak` -> `assert`
- `__declspec(align)` -> `alignas`
- `sprintf_s` -> `snprintf`
- `_aligned_malloc` -> `aligned_alloc`
- `QueryPerformanceCounter` -> `chrono`
- `LARGE_INTEGER` -> `int64_t`
- conditionally add `__stdcall`

- use correct case
- remove/fix Windows-only headers

This chapter requires libapophenia. It can be found on
http://apophenia.info/. After downloading, extracting and compiling, the
Makefile has to be tweaked, adding the appropriate -I and -L flags to
CFLAGS and LDFLAGS (respectively).

Corretions.
