This means you can use the "LONGARGS" option in GNU-ish make.  It's
not intended for direct use.

If you use GPL code, you must comply with the GPL.  In 1.09, all GPL
code is in libgcc.a.  See source files for actual copyright
information.  The mere act of compiling causes no restrictions.
Nothing in libc.a or libm.a incur any restrictions either - everything
is mine or BSD.

Correct.  You may also prepend stub.exe without incurring any
restrictions.  You may also ship emu387 without (preferably with,
though) sources.

Incorrect.  If you use the C++ classes in libgcc.a, *then* you must
comply with the LGPL, which requires you to ship at least object
modules and libgcc.a sources, so that the end user may rebuild
libgcc.a and relink your application.

Hence the LGPL.  I don't recall if I included a copy with libgcc.a,
but if you can't ftp prep.ai.mit.edu then I'll send you a copy.
