[RFA] "ln -s" in gdb/doc/Makefile
- To: gdb-patches at sourceware dot cygnus dot com
- Subject: [RFA] "ln -s" in gdb/doc/Makefile
- From: Eli Zaretskii <eliz at delorie dot com>

- Reply-to: Eli Zaretskii <eliz at is dot elta dot co dot il>
doc/Makefile invokes "ln -s" unconditionally, but the DJGPP port of ln
supports symlinks only for executables, and does the wrong thing in this
case.
Okay to commit?

* Makefile.in (LN_S): Define.
(gdb-cfg.texi, gdb.dvi, links2roff, inc-hist.texinfo): Don't
invoke "ln -s" unless it is known to work.
* configure.in (AC_PROG_LN_S): Add.
