Inspired by this commit, I made the following commit to blead:

     embed.fnc: Remove inappropriate pure attributes
     
     In looking at the diffs from f6e4c377437f9b2ded79fb55f66983a6d4f761f9,
     just committed, I realized that some of the functions marked pure,
     really have side effects, if only initialization if not called
     previously.  Still, the compiler could optimize things so it is wrong.
     I then did a manual audit of embed.fnc, and removed the pure attribute
     of the functions that I found that have some potential side effects.
