        PR fortran/46625
        * gdtoa/gdtoaimp.h: Mangle internal functions by
        prefixing them with __quadmath. Don't use gdtoa's strcp(y).
        * gdtoa/g_Qfmt.c (g_Qfmt): Use strcpy instead of strcp.
        * gdtoa/misc.c (strcpy): Renamed from strcp and only use
        if NO_STRING_H is set.
        * quadmath-imp.h (__quadmath_rem_pio2q,
        * __quadmath_kernel_sincosq
        __quadmath_kernel_sinq, __quadmath_kernel_cosq): Added
        __quadmath prefix to internal functions.
        * math/cosq.c (cosq): Ditto.
        * math/sinq.c (cosq): Ditto.
        * math/tanq.c (tanq,__quadmath_kernel_tanq): Ditto.
        * math/rem_pio2q.c (rem_pio2, __quadmath_kernel_rem_pio2):
        * Ditto.
        * math/sinq_kernel.c (__quadmath_kernel_sinq): Ditto.
        * math/cosq_kernel.c (__quadmath_kernel_cosq): Ditto.
