2008-04-23id: do print the AFS-specific nameless group ID (called a PAG)Jim Meyering
In 6.11, we mistakenly suppressed the printing of certain group IDs, thinking they were useless AFS-specific artifacts.

Revert "Work around AFS bug: id and groups would print invalid group number." This reverts commit b7a836c0a3524cda8ef79c30c3fe7ea759ae4656. Revert "* src/c99-to-c89.diff: Accommodate a C99-ism in id.c." This reverts commit d44893c5dba4150b4ded9cf6aad316c1ef620c9f.
