I suspect glib would want std=gnu99 not std=c99, but yes, there are
many packages in the archive that pick their std via upstream auto
fudgery, and glib likely should be doing this.

In some future GCC version, gnu99 will almost certainly be the default,
but that future isn't here yet, and people needing adherence to a
standard should pick it manually regardless.
