Re: Override default CXXFLAGS

[Sergio Belkin]

I answer myself: RTMF :)

"If using the GNU C compiler, set shell variable GCC to ‘yes’. If
output variable CFLAGS was not already set, set it to -g -O2 for the
GNU C compiler (-O2 on systems where GCC does not accept -g), or -g
for other compilers. If your package does not like this default, then
it is acceptable to insert the line ‘: ${CFLAGS=""}’ after AC_INIT and
before AC_PROG_CC to select an empty default instead. "
