`configure.ac' to allow users to better control the list of supported languages. Three LT_INIT options 'no-lang', 'all-lang' and 'auto-lang' (the default) control the initial list and others may be added with LT_LANG. * m4/libtool.m4 (_LT_CONFIG): Renamed AC_LIBTOOL_CONFIG to _LT_CONFIG which is more consistent with our own namespace and gets us further out of Autoconf's. (_LT_LIBTOOL_TAGS): Output available_tags variable based entirely on the value of _LT_TAGS. (_LT_COPYING): Call _LT_LIBTOOL_TAGS to output available tags, always append tag configuration if the tag is available. (LT_LANG): New macro to enable support for a language that accepts tag names (eg. "CXX") or human language names (eg. "C++"). (_LT_LANG): Internal support macro for above that appends the tag to _LT_TAGS and calls the appropriate config macro. (LT_INIT): Ensure that LT_LANG is not called before LT_INIT. (AC_LIBTOOL_TAGS): Removed, call LT_LANG for each language now. (_LT_AC_TAG_CHECK): Removed, _LT_LANG handles duplicate calls. (_LT_LANG_DEFAULT_CONFIG): Macro to set initial language support based on options passed to LT_INIT. (_LT_SETUP): Call _LT_LANG_DEFAULT_CONFIG. (_LT_AC_TAG_CONFIG): Removed, handled by _LT_LANG_DEFAULT_CONFIG. (_LT_AC_LANG_CXX, _LT_AC_LANG_F77, _LT_AC_LANG_GCJ): Removed, automatic language support inclusion now handled by _LT_LANG_DEFAULT_CONFIG. (AC_LIBTOOL_CXX): Obsolete macro, update to LT_LANG(C++). (AC_LIBTOOL_F77): Obsolete macro, update to LT_LANG(Fortran 77). (AC_LIBTOOL_GCJ): Obsolete macro, update to LT_LANG(Java). (AC_LIBTOOL_LANG_C_CONFIG_: Removed. (_LT_AC_LANG_C_CONFIG): Renamed to _LT_LANG_C_CONFIG, call _LT_CONFIG instead of AC_LIBTOOL_CONFIG. (_LT_SETUP): Replace call to AC_LIBTOOL_LANG_C_CONFIG with call to new _LT_LANG_C_CONFIG macro. (AC_LIBTOOL_LANG_CXX_CONFIG): Removed. (_LT_AC_LANG_CXX_CONFIG): Renamed to _LT_LANG_CXX_CONFIG, call _LT_CONFIG instead of AC_LIBTOOL_CONFIG. (AC_LIBTOOL_LANG_F77_CONFIG): Removed. (_LT_AC_LANG_F77_CONFIG): Renamed to _LT_LANG_F77_CONFIG, call _LT_CONFIG instead of AC_LIBTOOL_CONFIG. (AC_LIBTOOL_LANG_GCJ_CONFIG): Removed. (_LT_AC_LANG_GCJ_CONFIG): Renamed to _LT_LANG_GCJ_CONFIG, call _LT_CONFIG instead of AC_LIBTOOL_CONFIG. (AC_LIBTOOL_LANG_RC_CONFIG): Removed. (_LT_AC_LANG_RC_CONFIG): Renamed to _LT_LANG_RC_CONFIG, call _LT_CONFIG instead of AC_LIBTOOL_CONFIG. (LT_AC_PROG_GCJ): Renamed to LT_PROG_GCJ. (LT_AC_PROG_RC): Renamed to LT_PROG_RC. * m4/ltoptions.m4: Define new 'no-lang', 'auto-lang' and 'all-lang' options which set the default for _LT_LANG_DEFAULT_CONFIG. * m4/lt~obsolete.m4: Removed AC_LIBTOOL_CONFIG, _LT_AC_LANG_C_CONFIG, _LT_AC_LANG_GCJ_CONFIG, _LT_AC_LANG_RC_CONFIG; all of which are no long referenced in any way. * configure.ac: Enable all languages. * tests/cdemo/configure.ac, tests/demo/configure,ac, tests/depdemo/configure.ac, tests/f77demo/configure.ac, tests/mdemo/configure.ac, tests/pdemo/configure,ac, tests/tagdemo/configure.ac: Remove calls to AC_LIBTOOL_TAGS, the default 'auto-lang' mode now does the right thing. * doc/libtool.texi (The LT_INIT macro): Add documentation for new LT_INIT options and the LT_LANG macro, replacing the old documentation of AC_LIBTOOL_TAGS which is no more. * NEWS: Updated.

# AC_EXEEXT macros only works for C compilers!

# Libtool's setup macro calls AC_OBJEXT and AC_EXEEXT without setting

|
# the test language to C. We do it before any libtool setup macros are
|
|
# called so that the proper values are cached beforehand. We also do
|
|
# it before any linker flags (LDFLAGS) are set so that fortran specific
|
|
# ones don't break the tests.
