paths which avoid using short seeks on streams (especially
useful when the stream might be interactive or a pipe). At
the moment, this alternate path only avoids seeking when the
``buffer size'' of underflow() is 1 since the C standard only
guarantees buffer space for one ungetc (this technique could
be extended since *-*-solaris* supports buffering for 4 calls
to ungetc and *-*-*bsd* supports buffering limited only by
memory resources). Also, _GLIBCPP_AVOID_FSEEK must be defined
in a port's os_defines.h file for this alternate path to even
be considered. As a bonus, the idiom of using getc/ungetc
requires no system calls whereas fseek maps to one or two
system call(s) on many platforms.
