Dear Team,
I am trying to build 4.8.1 libstdc++-v3 library and I am seeing some
compilation errors. Please help.
Also, I was able to compile libgcc successfully.
GCC configuration used as :

../../../../gcc-4.8/libstdc++-v3/libsupc++/tinfo.h:25:20: fatal error:
typeinfo: No such file or directory
I checked but typeinfo file does not physically exist at below location.
gcc-4.8/libstdc++-v3/libsupc++/
I also tried to copy this file "typeinfo" from my older toolchain 4.3.3 but it
starts to fail further for "exception" file not found.
I again copied "exception" file from my older toolchain 4.3.3 but it again
fails further at :
error: '_GLIBCXX_END_NAMESPACE' does not name a type.
Any help in this regard will be appreciated.
Thanks.
Sumit
