# Brief problem description
# C source file - 'printf("Test");' added as diagnostics
# Source compiles and executes in Ubuntu
# Executable compiled in cygwin terminal OK in command prompt W8.1
# - Also OK in another machine running Windows 8.1
# Same executable in cygwin term waits for input before usage hint
