Please re-send these patches (updated to current mainline). I'm not
qualified to review or approve those parts of the implementation outside
the C front end, but I'll try to look at them and comment, especially if
they include documentation (of cases where something is
implementation-defined, and of any GCC extensions) and testcases for the
testsuite (gcc.c-torture/execute/ieee/, probably).

These pragmas aren't part of the preprocessor and are outside my
competence, and not much else has been done lately in the way of C99
implementation (a few important bits have been done by other people
though, e.g. flexible array members and C99 designated initializers) so
aren't within the scope of any recent C99 implementation work.
