The automatic concatenation of strings is a feature that has been introduced
by the ANSI comittee.  It is actually quite useful when you want to do something
like:
     #define CSI "\x9B"
     #define EEOL CSI "K"
     printf(EEOL "This is a string" );
With the ANSI standard recently voted out, expect to see more compilers
performing this type of operation, not less.
