Currenlty - only version informations to be included to my programs.

Some guestions that I encounter reading docs :


<cit>
`__USING_SJLJ_EXCEPTIONS__'
     This macro is defined, with value 1, if the compiler uses the old
     mechanism based on `setjmp' and `longjmp' for exception handling.
</cit>

what - is the new mechanism ?


<cit>
     Another approach is to use the predefined macros to calculate a
     single number, then compare that against a threshold:

          #define GCC_VERSION (__GNUC__ * 10000 \
                               + __GNUC_MINOR__ * 100 \
                               + __GNUC_PATCHLEVEL__)
          ...
          /* Test for GCC > 3.2.0 */
          #if GCC_VERSION > 30200 
</cit>

GNUC ver. i s stored in 'float' version, like :
3.00.00
  after big path:
3.00.50
  after small path :
3.00.51

OR :
3.0.0
  patch
3.0.1
  path
3.0.2

etc ?
