/***
*int _filbuf(stream) - fill buffer and get first character
*
*Purpose:
*	get a buffer if the file doesn't have one, read into it, return first
*	char. try to get a buffer, if a user buffer is not assigned. called
*	only from getc; intended for use only within library. assume no input
*	stream is to remain unbuffered when memory is available unless it is
*	marked _IONBF. at worst, give it a single char buffer. the need for a
*	buffer, no matter how small, becomes evident when we consider the
*	ungetc's necessary in scanf
*
*Entry:
*	FILE *stream - stream to read from
*
*Exit:
*	returns first character from buffer (next character to be read)
*	returns EOF if the FILE is actually a string, or not open for reading,
*	or if open for writing or if no more chars to read.
*	all fields in FILE structure may be changed except _file.
*
*Exceptions:
*
