No, it's not.  See ISO/IEC 14882:1998(E) Section 5, Expressions,
Para. 9.

Hi.
I took a look there, now it is ok with me.
But suppose I want to review all places in my code where

1) There is an addition or a substraction between signed and unsigned int.
2) Assignment from one to other.

I know that GCC can warn me of 'signed' vs. 'unsigned'
comparison. Is there any simple way to find the others ?

Thanks, regards,
Dima.
