It seems M_2_SQRTPI[lq] are GNU extensions, thus missing in Solaris
<math.h>. The following patch at least allows Solaris bootstrap to
continue:
The patch is looks good to me.
diff --git a/libgfortran/intrinsics/erfc_scaled.c
b/libgfortran/intrinsics/erfc_scaled.c

I suppose the same should be done for M_2_SQRTPIq?
I don't think so. That's defined in libquadmath's quadmath.h, which is
