I'm currently compiling my linux based of the Linux From Scratch SVN.
I decided to try my hand at compiling with the gcc 4.3.0.
The current bug im noticing has to do with the -O2 flag and __cplusplus.
I have done a search through the bug database all most errors that I have seen
have had __cplusplus in the part of the program that failed.
One of the programs that I tried to compile was tar 1.18 and 1.19. It would not
compile because of the -O2 flag, when I removed it from the config script and
reconfigured it compiled fine.
The same thing happened with the glibc and the problem was in the conftest
which had a __cplusplus and a exception throw.
With LFS the first part of the compiling process is to only comprile the C
compiler part of gnu compiler yet im not sure why __cplusplus would be
returning true if there is not a C++ compiler.
