Hello,
The following source file fails to compile with g++ on SuSE Linux 9
ia32 but compiles without error if I use gcc.
Let me know if I can collect any additional information. I have read in
the gcc manuals that an empty attribute-list should be ignored so this
seems like a bug but I searched through hundreds of bugzilla bugs and
didn't find this.
Should I post this to a different mailing list?
Cheers,
scott rankin
