I certainly agree that I abused the macro. However, many people were using the alignment attribute to request alignments that the linker wasn't capable of providing without -fno-common. This is critical for when the decl is used for a semaphore lock. They require 16-byte alignment on the PA. Also, I believe -fno-common only applies to C. Thus, I think the above suggestion is a good one but the ada routine doesn't have access to the decl. The only other solution that I can see is to give up using common for uninitialized data.
