Like AC_GNU_SOURCE, gl_USE_SYSTEM_EXTENSIONS must be mentioned early in the
configure files. When using
"./gnulib-tool --create-testdir --dir=/tmp/testdir alloca fnmatch-gnu"
I now get the following warning from 'autoheader' and 'autoconf':

configure.ac:22: warning: AC_COMPILE_IFELSE was called before 
gl_USE_SYSTEM_EXTENSIONS
configure.ac:22: warning: AC_RUN_IFELSE was called before 
gl_USE_SYSTEM_EXTENSIONS

To fix this for users of gnulib-tool, I've committed this fix.

2003-08-17  Bruno Haible  <address@hidden>

        * gnulib-tool (func_create_testdir): Handle gl_USE_SYSTEM_EXTENSIONS
        like AC_GNU_SOURCE.
        * modules/extensions (configure.ac): Comment out the invocation of
        gl_USE_SYSTEM_EXTENSIONS.
