At this time, there is one libstdc++-v3-specific macro which may be defined. _G_USING_THUNKS 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). -_GLIBCPP_AVOID_FSEEK 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*, -sparc-sun-solaris2.* and *-*-mingw32*. +invalidates the assumption that some ports don't use thunks).
