Thanks, that solved the configure problem.
Now I got another, where has sys_errlist.h gone,
and how do I resolve this:

Since the header file is the same as last time:
# md5sum work/ngspice-27/src/include/ngspice/ngspice.h
/usr/include/ngspice/ngspice.h
e695c3d756b1b934563779766bfd7881 work/ngspice-27/src/include/ngspice/ngspice.h
e695c3d756b1b934563779766bfd7881 /usr/include/ngspice/ngspice.h
there must be something else at play here.
$ find /usr/include -type f -name \*.h | xargs grep sys_errlist
/usr/include/X11/Xw32defs.h:# define sys_errlist _sys_errlist
/usr/include/nspr/prerror.h:** (sys_errlist); this allows errno values to be
used directly in the
/usr/include/schily/errno.h:extern char *sys_errlist[];
/usr/include/ngspice/ngspice.h:#define perror(string) fprintf(stderr,"%s:
%s\n",string,sys_errlist[errno])
/usr/include/ngspice/ngspice.h:#define perror(string) fprintf(stderr, "%s:
%s\n", string, sys_errlist[errno])
$ grep sys_errlist.h /var/db/pkg/*/*/CONTENTS
$
I have a crosscompiler that has sys_errlist[]:
/home/local/gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf/arm-linux-gnueabihf/libc/usr/include/stdio.h:#include

extern int sys_nerr;
