Hi


Here is a solution to the compilation problem, I am not sure if you 
accept it or if it is a bad one.

The idea behind the solution is to to check for the platform call 
adjtimex as well, in parallel with the check for __adjtimex.

The build system will favouring __adjtimex before adjtimex.

Essential ./configure will add the #define HAVE_ADJTIMEX 1 to config.h 
if it found the system call adjtimex in the same way when ./configure add
#define HAVE___ADJTIMEX 1 to config.h if it find __adjtimex


------ 

#### File configure.ac, at line 681 insert the following

case "$host" in
 *-*-*linux*)
    AC_CHECK_FUNCS([adjtimex ntp_gettime])
    ;;
esac


#### File .../util/tickadj.c line 24, replace #ifdef HAVE___ADJTIMEX with 

#if defined (HAVE___ADJTIMEX) || defined (HAVE_ADJTIMEX) /* Linux */


#### File .../util/tickadj.c line 94 and 149, replace if (__adjtimex(&txc) < 0)
with 

#ifdef HAVE___ADJTIMEX
        if (__adjtimex(&txc) < 0) 
#else
        if (adjtimex(&txc) < 0)
#endif



----

This solves the compilation error on my platform and make tickadj work.

# tickadj
tick = 9960

# tickadj 9900
tick = 9900

# tickadj 9960
tick = 9960
