The message "mathvec needs GCC version 4.5 or later" is not appropriate in current glibc; glibc already requires GCC 6.2 or later to build. Is this configure test for compiler support actually needed, or does it suffice to build all the relevant files with -mvsx? That is, are there any 64-bit configurations where -mvsx would produce a compilation error? -- Joseph S. Myers joseph@codesourcery.com
