# This script creates a list of data types where each type is followed

# by the C++ mangled name for that type.  That list is then compared

# against the list in the c++-types.data file for the platform being

# checked.  Any difference between the two would mean that the C++ ABI

# had changed and that should not happen even if the change is compatible

# at the C language level.

#

# The list of data types has been created with

# cat <

# #include <unistd.h>

# #include <sys/resource.h>

# #include <sys/stat.h>
