thank you very much for testing this package. Unfortunately I do not 
have a running linux system here and have never used the synthetic 
target before. So I can test uSTL only with arm-eabi toolchain.

It would be really great, If you could investigate a little bit more, 
what causes the SIGSEG for synthetic target. Would you be so kind to run 
the new snprintf_c99.c test on synthetic target when C99 compliance 
activated to check if my vfnprintf() patch is working properly?

This would be really great.

If there would be a preconfigured VM linux image available on the eCos 
homapage with all tools installed and a working synthetic target I would 
immediatelly start testing ;O)

Kind regards, Uwe
