cygwin fails

[Benjamin Kosnik]

David, I'm unable to work on this, sorry.

I suggest
1) linking statically (-static)
2) rebuilding libstdc++ with 'make CXXFLAGS='-g -O0' all'

and then trying to debug a full testcase that is failing, trying to find 
out where VERIFY (ie assert) goes bad.

I've finally got a cygwin build, and now I have to leave. 

At the same time, simple executables like

std::filebuf fb01;

and 

std::string str("hail canada");
std::istringstream iss(str);

compile and link, run without problems. Looking at this stuff in gdb 
shows this odd memory error, but only after the executable has exited. 
So, I don't think that is the problem.

I had problems building the first FAIL case, 
21_strings/inserters_extractors.cc. This seems due to some oddness in my 
install. Sorry.
