AppleWin/source/Util_MemoryTextFile.cpp
tomch f24971f582 Merge from Tom: r683
Added Speech API support:
. Capture char output to COUT
. Enable speech via -speech cmd-line
. Ctrl+Reset and FullSpeed mode purge the speech buffers
Removed #pragma hdrstop from all .cpp files except AppleWin.cpp (which is the PCH create file)
