Re: GCC 4.8.0 Build Failed.

Hi,

I guess these errors are propagating from systemmap sdt.h file. I made
some changes in this header file to avoid compiler error explained
above.Some one told me to use the upgrade version of systemmap for
building gcc 4.8.0, but what i found we are using some macros defined
in sdt.h,

here is the diff of installed systemmap and systemmap-2.0(new one)
section which matter in this case..

I just propagated these changes in installed sdt.h file, i solved
compiler error, but I guess i made mess while linking.

Any suggestion, are these changes are cause of linker error.....
