This compiler may well build for the 68k but the maintenance up to the
point we got it was all directed for to the ppc architectures.  

Could also be that the error affects the "I" code side of the compiler
and would thus get most/all of its supported architectures.

Anyone see this error on other architectures i.e. PPC?

Subject: t202/SNS-patched 68K compiler bug

FYI,

There is a compiler error in the t202/SNS-patched compiler
(cross-gcc-2.7.2-patched.tar.gz) for 68K target architectures.

This error is exhibited when invoking MPF's R1-10
tcpMessageRouterServerStart() function from a st.cmd file.

Under these conditions (i.e.,
- t202/SNS-patched compiler
- 68040 target architecture
- MPF R1-10
tcpMessageRouterServerStart() starts the "TcpClient" task
instead of the "TcpServer" task.

This compiler error has to do with how the "bool" variable,
"isServer" is allocated in tcpMessageRouterServerStart()
(byte or word) and passed from the C++ creator Tcp::Tcp()
to the TcpPrivate creator TcpPrivate::TcpPrivate().

The fix here at APS was to recompile RMRServer.cc and Tcp.cc
in mfpApp/kernelSrc using WRS's compiler.
