[coyotos-dev] BigNum.cxx buglet?

[Thomas Stratmann]

I have a working version here, which means that capidl is neither 
crashing nor looping endlessly. It is the result of the patch I sent 
previously plus the one attached.

However, compiling coyotos gives the following error:

/usr/bin/ccache /coyotos/host/bin/i386-unknown-coyotos-gcc -g 
-finline-limit=3000 -fno-strict-aliasing -I../../../../../sys

(sorry for using a localized compiler --  the first warning means 
integer constant too big for unsigned long)

I'm afraid I am missing the understanding of implementation details to 
understand where this might come from. I put an assertion in

   BigNum::BigNum(size_t _nDigits, uint32_t* _digits, bool _negative)

to catch BigNums being constructed with more than two effective digits, 
but it was not triggered.
