I know.
Unluckily if I do this, changing the semantic in a way
that EOS/EOF means POS > SIZE instead of POS >= SIZE,
it fails everywhere else...
It cannot even read Scummvm.ini anymore :-(
Other backends (notably the DS) have a ">=" semantic:
see std_feof in backends/fs/ds/ds-fs.cpp
return handle->pos >= handle->size;
For me it's:
a) EOF means "POS > SIZE" -> snafu
(can't pass ConfigManager::loadFromStream)
b) EOF means "POS >= SIZE" -> lose themes, cant's start Indy4, etc.
(unless I disable the "eos" check part in ::ioFailed which is
what I plan to do shortly [I already know it works] ;-)
If you have any suggestions they are welcome,
Thanks!
