You use if() instead of #ifdef, and TenDRA do dead code elmination at install time. BTW: I just found out that TenDRA _do_ support __asm(). This is supported to a limited degree in the C frontend (it can only send a pure string to the backend, which will typically insert it in the asm output). I'm not certain if this is enough for our needs. > >>> * Better error checking/control > >> How do you mean? > > Full mapping of the error checking and warning space.

Another neat part of this is that TenDRA indicate what you're in violation of by ISO section - always nice when you have to hit some Linuxer over the head with his violation ;-) Eivind.
