beta release.
kes Make make clean decend into the src/win32 directory.
kes Fix some #ifdefing so that Solaris and FreeBSD compile
sys/stat.h was turned off.
kes Use suffix editing for new transfer rate messages.
kes Attempt to come up with a workaround which seems to be an OS
bug where write() returns EBUSY. IMO this should not happen.
It triggered in truncatebug test. The workaround retries using
a 100 ms wait.
kes Eliminate a strerror() call in a class method that failed with
older C++ compilers.
kes Use rm -rf rather than rmdir to delete the src/win32/release
directory during make clean.
