Tnhanks for your report. Andries confirms you are correct,
and I've amended the man page for 2.41; see below.

CLOG10(3) complex math routines CLOG10(3)
NAME
clog10, clog10f, clog10l - base-10 logarithm of a com-
plex number
SYNOPSIS
#define _GNU_SOURCE
#include <complex.h>
double complex clog10(double complex z);
float complex clog10f(float complex z);
long double complex clog10l(long double complex z);
Link with -lm.
DESCRIPTION
The call clog10(z) is equvalent to clog10(z)/log(10).
The other functions perform the same task for float
and long double.
Note that z close to zero will cause an overflow.
CONFORMING TO
This function is a GNU extension. It is reserved for
future use in C99.
