* ltconfig.in (LD): Same as below.
|
||||
|
||||
* libtool.m4 (LD): Set LD if we discover an absolute path to GNU
|
||||
ld. This avoids unnecessary tests. Reported by Ulrich Drepper.
|
||||
|
||||
* ltconfig.in: Port to OS/2 using EMX. From Jeff Freedman.
|
||||
(double_quote_subst): sed substitution to protect metacharacters
|
||||
in variables that are evaled twice.
|
||||
|
||||
* ltmain.in (link): Use old_archive_from_new_cmds.
|
||||
|
||||
* ltconfig.in (old_archive_from_new_cmds): New variable to
|
||||
support DLL libraries.
|
||||
|
||||
* ltmain.in (link): Only `eval' export_dynamic_flag_spec if it is
|
||||
not empty. Reported by Stephan Kulow.

* Allow configure.in to change the defaults for AM_PROG_LIBTOOL's

`--enable-shared' and `--enable-static' flags by setting

the `enable_shared' or `enable_static' shell variables to `no'.
