/*This program should print either two normal v's, if \v is notrecognized as an escape sequence for the vertical tab (control-K), ortwo control-K's, if it is.On siesta.wustl.edu and ritz.cec.wustl.edu (both running Solaris 2.3or 2.4), compiling with GCC 2.6.0, this program prints a v followedby a control-K.  I don't know yet if this is a problem with GCC 2.6.0in general, or only on this operating system, or only because of someoption that was set badly when it was compiled on these systems.On leia.wustl.edu (running SunOS 4.1.4), compiling GCC 2.5.8, thisprogram prints two control-K's.I tried out GCC 2.7.0 on my home Linux machine, and it worked correctly(printing two control-K's).*/main(){    char str1[2];    char str2[2];    strcpy(str1, "\v");    str2[0] = '\v';    str2[1] = '\0';    printf("%s", str1);    printf("%s", str2);}
