My guess is it was a simple cost/benefits analysis.  Here is
a compiler (not language!) feature that is of dubious utility,
probably not used very much, and requiring further investment
of effort to support for new OS releases, changes to object
file formats, etc.  It isn't surprising that gcc developers
might decide their efforts were better spent elsewhere - just
yank the thing and be done with it, especially since there
are easy and obvious workarounds, and even easier given that
support for compound literals in C99 had been around for five
years at that point.
