re PR libstdc++/8610 (large file support in libstdc++-v3 (std::streamoff type is 32-bit in GCC 3.2 whereas it was 64-bit in GCC 2.96)) 

2003-10-22  Paolo Carlini  <pcarlini@suse.de>

	PR libstdc++/8610
	* acinclude.m4 (GLIBCXX_CHECK_INT64_T): New macro,
	checking for the availability of int64_t.
	(GLIBCXX_CHECK_LFS): New macro, checking for LFS support.
	* configure.ac: Call here.
	* acconfig.h: Add undef for the corresponding symbols.
	* config/io/basic_file_stdio.cc	(__basic_file<char>::open):
	Depending on _GLIBCXX_USE_LFS, call fopen64 or fopen.
	(__basic_file<char>::seekoff): Likewise, call lseek64 when
	available, otherwise lseek, checking the __off parameter.
	* include/bits/postypes.h: Typedef __streamoff_base_type
	to int64_t if available, otherwise long long.
	* aclocal.m4: Regenerate.
	* config.h.in: Likewise.
	* configure: Likewise.

	* acinclude.m4 (GLIBCXX_CHECK_POLL, GLIBCXX_CHECK_WRITEV):
	Use AC_TRY_LINK instead of AC_TRY_COMPILE.
