* demo/Makefile.am: moved testsuite specific declarations to the end,
|
||||
the deplibs check is now optional
|
||||
* libltdl/configure.in: read libtool --config only once,
|
||||
merged AC_SYS_SYMBOL_UNDERSCORE+AC_SYS_NM_PARSE from libtool.m4
|
||||
* libtool.m4: AC_SYS_SYMBOL_UNDERSCORE+AC_SYS_NM_PARSE were not
|
||||
used, lt_dlopen and silent may be empty, AC_SYS_LIBTOOL_CYGWIN
|
||||
no longer necessary
|
||||
* ltconfig.in: NM is already checked in libtool.m4,
|
||||
* ltmain.in: always link all static dependency_libs
|
||||
* tests/Makefile.am: added deplibs.test
|
||||
* tests/demo-exec.test, demo-inst.test: removed hell0
|
||||
* tests/deplibs.test: new test to test the deplibs_check_method
|
