GCC is viewed as being able to debug (-g) and optimize (-O2) at the
same time without any detriment.  Then if you want to strip the binary
to remove the debug information you can.  The make target to install
and strip is 'install-strip'.  Therefore the default is generally

If the compiler is not GCC then it only adds debugging (-g) and stops
there since most compilers can't do both at the same time.

If you want to change this you can set CXXFLAGS at configure time.

  CFLAGS=-O CXXFLAGS=-O ./configure

Those quasi-legal scare footers are both worthless and annoying.
Please try to convince your company to remove them.  Alternately send
mail from other accounts which do not have them.
