* demo/Makefile.am (hell_debug_LDFLAGS): Change hell.static to
|
||||
hell.debug in order to reflect the new static linking semantics.
|
||||
|
||||
* ltmain.sh.in (link): Add new `-all-static' flag to prevent all
|
||||
dynamic linking. The old `-static' flag just prevents dynamic
|
||||
linking against libtool libraries. Suggested by Bengt
|
||||
Martensson.
|
||||
|
||||
* ltconfig.in (with_gnu_ld): Add a test to make sure that we are
|
||||
actually using GNU ld. This fixes an inconsistency when running
|
||||
ltconfig without using libtool.m4. Reported by Ulrich Drepper.
|
||||
(global_symbol_pipe): Delete symbols that are not valid C
|
||||
identifiers. Reported by Johan Danielsson and Bengt Martensson.

test fails on Digital Unix 4.0. From Todd Kover.

* New `-all-static' flag to prevent any dynamic linking. The regular
