This is not something we can easily fix. You see that the cited
strcspn declarations are the same, yet they "conflict". I guess
problem is that the one in /usr/include/iso/string_iso.h is not
in the "C" namespace.

Generally, these C++ tests are supported on glibc systems with
modern GCC. For testing Solaris 10, try passing the option
'--without-c++-tests' to gnulib-tool.
