Can you at least be specific about the errors? It is rather frustrating
reading your emails, being so vague about and all. Are you mixing Cygwin
and mingw code?

   Sorry. I was remiss.

   Execution fails on all of the mingw compilers with the same error
   message. All compilations use the same command line options.

   > i686-pc-mingw32-g++ -Wall -Wno-reorder -Wno-unused-value -DYYDEBUG=1 
     -DDEBUG_IO   -c -g -MMD -MP -MF

   > slip.exe

/E/home/skidmarks/Projects/SLIP/slip/dist/Debug/mingw-Windows/slip.exe:
error while loading shared libraries: libstdc++-6.dll: cannot open shared
object file: No such file or directory

RUN FAILED (exit value 127, total time: 15ms)

After execution I ran the following find on /usr.

> find /usr/i686-pc-cygwin 
       /usr/i686-pc-mingw32 
       /usr/i686-w64-mingw32 
       /usr/x86_64-w64-mingw32 -iname 'libstdc++-6.dll'

i686-pc-mingw32/sys-root/mingw/bin/libstdc++-6.dll
i686-w64-mingw32/sys-root/mingw/bin/libstdc++-6.dll
x86_64-w64-mingw32/sys-root/mingw/bin/libstdc++-6.dll

/usr/i686-pc-cygwin apparently does not use this dll and the generated mingw
executables can not find it. Can anything be done about this - I refrain
from 'guessing', 'inferring', or 'assuming (causality)'.
