Description of problem:
Function btowc() in library libstdc++.so.5 contains an infinite recursion. See
disassembly, address 0x001b00da:

Version-Release number of selected component (if applicable):
Fedora Core release 4.92 (Pre-FC5)
Legacy Software Support packages:
compat-gcc-32-3.2.3-55.fc5.src.rpm
compat-gcc-32-debuginfo-3.2.3-55.fc5.i386.rpm
compat-libstdc++-33

How reproducible:
Compile example in RH9 or FC1. Output binary file depends on libstdc++.so.5
library. Run application on FC5 test3 or FC5.
If you compile example in FC5, output binary file will depend on libstdc++.so.6
and will use btowc symbol from libc.so.6. 
  
Actual results: 
Application will crash on stack overflow due to infinite recursion in function
btowc().

Expected results:
Application will not crash. Compat-lbstdc++-33 package will be truly compatible.


Example:
void test_local_date()
{
	time_t timestamp;
	struct tm *ta;

        time(&timestamp); 
	ta = localtime(&timestamp);
	std::locale *loc = new std::locale("cs");

	std::wstring format = "%x";
	std::wostringstream wstr;

	std::use_facet<std::time_put<wchar_t> >(*loc).put(wstr, wstr, wstr.fill(), ta,
format.data(), format.data() + format.length());

        delete loc;
}
