Re: eCos and Keil

Hi Stano,

I am playing with GCC 6.1 and it gives 20% beetter Coremark than GCC 4.9.

I would like to submit GCC 6.1 as a replacement for GCC 4.6 but there's
one important issue with GCC 5.0 and newer. Namely, they have adopted
GCC 11 as standard mode rather than 89. which mainly affects inlining.
For the time being I have solved this problem by enforcing 89 mode on
GCC, but I am in a dilemma whether to:

   1. Enforce mode 89 (as I do now)
   2. Make eCos to work in C11 mode. In this case I will need some help.

Regards

Ilija
