Fix for undefined (?) behaviour in fopenNoCase()
|Reported by:||eriktorbjorn||Owned by:||fingolfin|
There was some discussion on IRC about problems when compiling ScummVM with -O2. For instance, there was no opening cutscene in The Dig.
I can never remember which expressions are undefined and which aren't, but this patch fixes the problem for me.
