 I'd rather rely on an upstream-provided configure script, if possible.

 Is it OK that CPPFLAGS content ends up in CXXFLAGS?

 There is no CPP package as such on Arch Linux. cpp, gcc and g++
 executables come in a single GCC package here. It doesn't provide this
 `/lib/cpp' link.

 Anyway, I created /lib/cpp -> ../bin/cpp symlink manually, but this
 doesn't help and doesn't seem to be the actual issue. The references to a
 missing /lib/cpp link only got replaced by yet more "_FORTIFY_SOURCE
 requires compiling with optimization" warnings. The original errors
 remain:

 {{{
 /usr/include/sys/cdefs.h:30:3: error: #error "You need a ISO C conforming
 compiler to use the glibc headers"
 gcc: error: unrecognized command line option '-nologo'
 }}}

 I'm attaching a complete config.log-fail-with_cpp_symlink.
