Minor bug in libstdc++ compilation by make buildworld

[Kövesdán Gábor]

Hello there,

I was wondering why make buildworld fails and I found on some mailing 
list archives that one should comment CXXFLAGS out to fix this issue. I 
was also able to get around with this, but I've realized that the 
problem has nothing to do with code optimization. Even if I specify a 
CXXFLAGS=-O in make.conf the whole make buildworld fails. It certainly 
must be some kinda Makefile deficiency and as far I see it could be 
easily fixed by a programmer. And as I think it should be fixed. It 
would be nice to use optimized CPP flags and have a faster and optimized 
code. And many end-user would be happy to have this opportunity.
I'm looking forward to Your answer.

Best regards,

Gábor Kövesdán
