acconfig.h: _GLIBCPP_USING_THREADS and some workaround types added.

2000-08-23 Phil Edwards <pme@sourceware.cygnus.com> * acconfig.h: _GLIBCPP_USING_THREADS and some workaround types added. * acinclude.m4: New macro, GLIBCPP_ENABLE_WCHAR. Set the threads definition as well, and some minor spelling/spacing fixes. If building libio, check for certain typedefs. * libio/_G_config.h: Wrap _IO_MTSAFE_IO in _GLIBCPP_USING_THREADS. Conditionally define _LARGEFILE64_SOURCE, otherwise the 64-bit types will never be there. * libio/libio.h: In the null case, _IO_lock_t can't just be void. * src/string-inst.cc: Use _GLIBCPP_USE_WCHAR_T. * configure.in: Update the cache a bit more often. * mkcheck.in: For check-install, also need to -I the testsuite dir.
