Subject: 64-bit Windows compiler warnings doctokinizer.l

Removing compiler warnings like:
```
.../src/doctokenizer.l(101): warning C4267: '=': conversion from 'size_t' to 'int', possible loss of data
.../src/doctokenizer.l(844): warning C4267: 'initializing': conversion from 'size_t' to 'int', possible loss of data
...
```
(analogous as done in e.g. `commentscan.l`)
