Example code compiles, but shows errors unless <stdbool.h> is included.

On Windows with VS Code. "bool redraw = true" generates two errors:

1. function "redraw" may not be initialized.

2. identifier "true" is undefined.

Later assignments to the variable also generate "expression must be a modifiable lvalue".

It still compiles despite this, but this makes me hesitant to actually use allegro at this point.

In a similar vein, the install instructions should be updated, as mingw64 has a subdirectory with its own bin, include, and lib where allegro needs to be installed, rather than just the top level versions of those folders.

This is as mentioned (seemingly) fixed by including <stdbool.h>

Thanks, I've made those changes.
