However the fact that gcc is single-threaded means that gcc was build
with --enable-threads option off; this option enables C++ exception
handling for multi-threaded code. Does it mean that I should not use
exceptions in C++ code? But even if I don't myself, some parts of the
standard library could do it, e.g. new() throws  bad_alloc.
Also, how could you comment this:
[citation]
4. All C++ code compiled by gcc 3.X configured with --disable-threads.
   The final program is actually multi-threaded.

Undetectably broken.  It might work, or it might not, on any
particular run.  The most basic problem is that C++ exception handling
will not work properly.  Up the stack from there, standard C++ library
resources might get trashed.
