exp2 is part of the C99 standard, so it's certainly not deprecated and
also not something GNU-specific. Not all C compilers and C libraries
support C99, however, as I wrote before, we don't guarantee that all
functionality provided in the bindings is available on all platforms.
For example we already provide bindings for glib 2.15 functionality,
although this version is not yet widely installed.

Yes, something like that is planned to be added to Vala.
