  Alex,

I agree with you and Paul here:

I found something else that we can compare notes to.
Do a:

unset CPLUS_INCLUDE_PATH
`gcc -print-prog-name=cc1plus` -v

to show the g++ include paths irrespective of what CPLUS_INCLUDE_PATH
was set to. Be sure to use the correct type of quotes in the above
command. Both of the quotes are ` which is on the same key as the tilde ~
on most keyboards. And it seems one has to press ctl-C to get back to
the command prompt after "End of search list." is displayed.

I found this tip at:
https://askubuntu.com/questions/573417/where-are-header-files-for-gcc-located

So, this information from your gcc setup can then be compared to that
of others with recent BLFS systems and then we can see if something
is indeed different.


  Cheers,

  Mike
