Implement --warning-mode in SETUP.sh. The value of the

argument can be either "pedantic" or "old" (actually, or anything
else). In case of "pedantic" mode, use -ansi -pedantic compilation
flags. Fix the build to compile in pedantic mode. (Version 3 of
the patch, with after-review fixes)


BUILD/SETUP.sh:
  Implement --warning-mode in SETUP.sh. The value of the
  argument can be either "pedantic" or "old" (actually, or anything
  else). In case of "pedantic" mode, use -ansi -pedantic compilation
  flags.
BUILD/compile-pentium-debug-max-no-embedded:
  Rename base_max_configs to base_no_embedded_configs
BUILD/compile-pentium-debug-max:
  Use double quotes around $@
BUILD/compile-pentium-valgrind-max:
  Pass command line arguments to SETUP.sh. Allows calling
  compile-pentium-valgrind-max --warning-mode=pedantic
include/my_global.h:
  Remove an unnecessary ifdef: -pedantic hides the system-wide
  definition of ulong on Linux. In case there is no -pedantic, 
  the system-wide definition is available and HAVE_ULONG is defined
  by configure.
