defined. <code>_G_USING_THUNKS</code> may be defined to 0 to express that the
port doesn't use thunks (although it is unclear that this is still
useful since libio support isn't currently working and the g++ v3 ABI
invalidates the assumption that some ports don't use thunks).
<code>_GLIBCPP_AVOID_FSEEK</code> may be defined if seeking on an interactive
stream (or one hooked to a pipe) is not allowed by the OS. In this
case, getc()/ungetc() will be used at some key locations in the library
implementation instead of fseek(). Currently, the code path to avoid
fseek() is only enabled when the seek size is 1 character away from the
current stream position. This is known to improve *-unknown-freebsd*,
