5b79e16a32 Uniform const'ness of symlist variable lt_preloaded_symbols.
On some systems, lt_preloaded_symbols may not be declared
const due to relocation issues.  C99 requires qualification to
match for compatible declarations, so ensure we declare
const'ness in the same way everywhere; link-time optimization
may otherwise rightfully complain about inconsistencies.
Since ltdl.h may not depend upon config.h, rely on system
defines for choosing const'ness.

* NEWS: Update.
* doc/libtool.texi (Dlpreopening): Document this issue.
* libltdl/config/ltmain.m4sh (func_generate_dlsyms):
[__WINDOWS__, __CYGWIN__, _WIN32_WCE]: Define LT_DLSYM_CONST
according to system defines.  Remove old shell cruft.  Use
LT_DLSYM_CONST for lt_${my_prefix}_LTX_preloaded_symbols.
* libltdl/libltdl/lt_system.h (LT_DLSYM_CONST): Likewise,
define LT_DLSYM_CONST according to system defines.
* tests/demo/foo.h (LT_DLSYM_CONST): Likewise.
* tests/pdemo/foo.h (LT_DLSYM_CONST): Likewise.
* tests/demo/dlmain.c (lt_dlsymlist): Use LT_DLSYM_CONST.
* tests/pdemo/longer_file_name_dlmain.c (lt_dlsymlist):
Likewise.
* libltdl/m4/libtool.m4 (_LT_CMD_GLOBAL_SYMBOLS): Likewise
for configure test code.
* libltdl/ltdl.c (preloaded_symbols): Use LT_DLSYM_CONST.
