On: The Little C Function From Hell

[krollew]

It's standard behaviour or one compiler does so? Outside preprocessor char has another meaning? Thanks anyway.

[cperciva → krollew]

Outside of the preprocessor, the char type is a one-byte integer (whether it's signed or not is implementation-defined).

[krollew → cperciva]

So the good solution is make a test that finds it out, for example in configuration script and set proper preprocessor constant and test that constant instead.
