[Bug-gnulib] gnulib-tool port to Solaris 8

[Paul Eggert]

Joerg Schilling was having problems bootstrapping GNU tar from CVS on
Solaris 8.  I installed the following portability patch to gnulib-tool
to fix the problems that I deduced from his email.  One of the fixes
(for sed) is required for POSIX conformance and the other one (test
-h) is simple and increases portability (while retaining POSIX
conformance).

2003-09-17  Paul Eggert  <address@hidden>

        * gnulib-tool: Use "test -h", not "test -L", for portability
        to Solaris 8 /bin/sh.  (This bug is fixed in Solaris 9.)
        (tags_regexp): Remove, since \| doesn't conform to POSIX.
        (sed_extract_prog): Issue s commands one-by-one, rather than
        using \| in one s command.
