re PR libstdc++/9320 (Incorrect usage of traits_type::int_type in stdio_filebuf)

Browse Source 
2003-02-11  Paolo Carlini  <pcarlini@unitus.it>

	PR libstdc++/9320
	* include/ext/stdio_filebuf.h
	(stdio_filebuf(int, std::ios_base::openmode, bool, int_type),
	stdio_filebuf(std::__c_file*, std::ios_base::openmode, int_type)):
	Change to take a __size parameter of type size_t, not
	of type (template parameter dependent) int_type.
	* src/ios.cc (ios_base::Init::_S_ios_create): Change type of
	size vars to size_t.
	* testsuite/ext/stdio_filebuf.cc: Add.
