The old -mno-cygwin yielded a standalone executable that I could give to 
a colleague and it would "just work"  on a Windows machine without 
cygwin.  It appears that now one must bundle at least one dll.  From a 
licensing standpoint, are these dll's any different from cygwin1.dll? 
Can they be distributed freely without bundling the source code?  If 
not, I might as well forget about mingw and just supply cygwin1.dll.
