* Makefile.am (libtool): Use $(SHELL) when invoking ltconfig.

* ltmain.in: Make the `--features' flag print out all configured

* libtool.m4: Pass ltconfig the undocumented --no-reexec flag,
|
||||
since we call it explicitly with CONFIG_SHELL.
|

|
||||
* ltconfig.in: Restart the script under a different shell if
|

CONFIG_SHELL is not /bin/sh. This way, people can use Bash if
|

they don't have a working echo program.

that the SunPRO 4.2 cc doesn't complain. From Bob Friesenhahn.
|

(gnu_ld_acts_native): Delete this variable. There is just too
|

much version skew to try to pretend GNU ld is the same as the
|

system ld. Reported by Ian Lance Taylor.

(hardcode_action): Don't bother relinking or aborting on systems

that are too dynamic to have a consistent hardcode method.
