Remove macro definition of rewind() which does not clear the IO error indicator.

Browse Source 
Now rewind() will always be called as a function. In combination with an update to the rewind() function in ORCALib, this will ensure that the error indicator is always cleared, as required by the C standards.

190. Calling rewind() should clear the I/O error indicator for the stream (the value returned by ferror()), but it was not doing so.

1. In some situations, fread() reread the first 1K or so of the file.
