I've used both C and Pascal in embedded systems. Pascal is painful compared to C. A "somewhat modified" version might help, but I doubt it would be enough. To steal a phrase from my friend Michael Pavlinch: Pascal was like picking your nose with boxing gloves on. A modified boxing glove isn't really going to solve the problem.
For that matter, once we weren't on Unix but rather on the PC, and we had a nicely-modified Pascal (Turbo Pascal), why did C/C++ win there, too?
