There is a compilation error while trying to compile systemtap using the
following gcc version:
gcc version 4.5.0 20090620 (experimental) [trunk revision 148747] (Debian
20090620-1)

...and many more
The cause of errors is use of macro POP() that creates variable declarations
inside switch in file loc2c.c.
