strtod_l and strtold_l are POSIX functions, which are supposed to be defined
by the system.

Here's a proposed fix:


2010-11-18  Bruno Haible  <address@hidden>

        c-strtold: Avoid link error on AIX 7.
        * lib/c-strtod.c: Test also HAVE_STRTOD_L or HAVE_STRTOLD_L.
        * m4/c-strtod.m4 (gl_C_STRTOD): Test whether strtod_l exists.
        (gl_C_STRTOLD): Test whether strtold_l exists.
        Reported by Albert Chin <address@hidden>.
