Subject: [PATCH] Avoid use of reserved C99 keyword "bool" as a variable name
MIME-Version: 1.0

gcc15 comes with -std=c23 by default. The C99 bool keyword is still
in effect. C23 has only deprecated it, not removed it.

gcc-15 output:

```
src/fplsa4.c: In function ‘ReadBooleanFromFile’:
src/fplsa4.c:7013:7: error: ‘bool’ cannot be used here
 7013 |   int bool;
src/fplsa4.c:7013:7: note: ‘bool’ is a keyword with ‘-std=c23’ onwards
src/fplsa4.c:7013:3: warning: useless type name in empty declaration
 7013 |   int bool;
```

gcc-14 output:

```
src/fplsa4.c: In function ‘ReadBooleanFromFile’:
src/fplsa4.c:7027:10: warning: ‘bool’ may be used uninitialized [-Wmaybe-uninitialized]
 7027 |   return bool;
```
