./configure doesn't really work for Solaris yet.
Sometimes someone sends in some patches to cope with some problems
that some of us on Solaris are experiencing.  I have installed automake
and browsed the docs especially for this purpose but I haven't been able
to solve it yet.

Well, I'm afraid you're treating this at the wrong end.  The problem is
definately in configure itself.

I use xmkmf on Solaris; with minor tweaking I can get a working compile.
For 1.7.1, my xmkmf recipe is this:

% xmkmf && make XPM_INCLUDE_DIR=/usr/local/include \
  SYS_LIBRARIES='-ldl -lintl' \
    LD_RUN_PATH=/usr/local/lib XPM_LIB_DIR='-ldl -lintl -L/usr/local/lib'

(Over here, xpm is installed in /usr/local.)

% ls -l /usr/include/string*
-rw-r--r--   1 bin      bin         3059 May  3  1996 /usr/include/string.h
-rw-r--r--   1 bin      bin          749 May  3  1996 /usr/include/strings.h
% grep strerror /usr/include/string*
/usr/include/string.h:extern char *strerror(int);

strerror() is there all right, on this Solaris box at least.
BTW I'm having a different problem: when I tell ./configure where to find
its XPM, it can no longer find the X11 libraries:

% setenv LD_LIBRARY_PATH /usr/local/lib:/usr/openwin/lib
% ./configure
loading cache ./config.cache
[...]
checking for X... libraries /usr/openwin/lib, headers /usr/openwin/include
[...]
checking for XOpenDisplay in -lX11... no
configure: error: Need X11
% setenv LD_LIBRARY_PATH /usr/openwin/lib
$ ./configure
[now it won't fail on XOpenDisplay, but it will fail on XPM
  which is in /usr/local/lib]
