Piotr, Hello. First, a note: you should be sending libstdc++ mail to the [EMAIL PROTECTED] list.
I haven't verified your claim, but if it is true, I would suggest the following actions on your part to solve it: 1) enter a sparc backend bug in gcc bugzilla about not defining __sparcv9 in 32 bit mode. Make sure the sparc maintainer is cc'd. (That would be Eric Botcazou). 2) enter a libstdc++ feature request in gcc bugzilla about 32bit atomic operations on sparc. Please include the atomic operations you've developed and would like to be part of libstdc++. I don't have access (or time) to deal with sun/sparc issues directly at the moment, but hopefully this will be useful to you. best, benjamin
