TODO list

here i keep bullets with future work that i want to do and write about:
  * find an answer for the following question: what is the shortcoming
  of old versions of gcc with regards to simplicity? why use them
  instead of a simple compiler developed later? some context:
  * do an analysis of the different interpretatoins of the ISO standard,
  e.g. gcc et al. decided to use the interpretation as a basis for
  optimisation, but what about other optimisations?
