Hey Benny!

 BP> its gentoo ?

its medevil.  I used to have one called minevil until gcc-4.7.x became
abandonware.  That was the last version where g++ wasn't a requirement.

 BP> python use flags is depricated

python as a dependency should be avoided methinks.

 BP> and now gcc 6.4 is minimal compiler

I think you still can get away with gcc-5 but I doubt for very long.  Maybe
another year or two.  Which gcc version are you currently using?

---- ":read !gcc --version" starts
gcc (GCC) 7.2.0

I notice that glibc-2.26 breaks a few things.  Nothing that I am using at the
moment.

Life is good,

... Don't cry for me I have vi.
