Detailed Description
This structure collects together a number of global variables.
This structure collects a number of global variables that mostly represent parameter settings for this compilation run. In particular, none of these values should change after compilation befins; their values are all set during command-line argument processing or very early during the compiler's execution, before any files are parsed.
