When I do this, today, I get no problem with <string.h> but with
<unistd.h>:

/tmp/clisp/src/gllib/unistd.h:46:22: error: token "@" is not valid in 
preprocessor expressions
/tmp/clisp/src/gllib/unistd.h:613:5: error: token "@" is not valid in 
preprocessor expressions
/tmp/clisp/src/gllib/unistd.h:735:5: error: token "@" is not valid in 
preprocessor expressions

The tokens @REPLACE_READLINK@, @GNULIB_LINKAT@, @GNULIB_SYMLINK@ were not
substituted. The reason is that configure is older than aclocal.m4:

$ ls -l src/configure src/aclocal.m4 
-rw-r--r-- 1 bruno users  712809 27. Sep 10:43 src/aclocal.m4
-rwxr-xr-x 1 bruno users 1824857 27. Sep 10:18 src/configure

The problem is that
  1) You don't have a dependency from configure to aclocal.m4,
  2) You are using an incomplete command:
       "make -f Makefile.devel gnulib-imported src/gllib/Makefile.in"

When I use a command that builds *all* prerequisites:

  make -f Makefile.devel gnulib-imported build-prerequisites

then src/configure is regenerated and all compiles fine.
