[PD] creb compilation error woes

[Thomas Greg Corcoran]

Mr. Peach,

thanks for you patience and suggestions

after a bit of fiddling it turns out that changing that function's definition:

to this:  [line 91]  static inline float _play_voice_lint(float
*table, int index, float frac, float scale)

seeems to make stuff work.

thanks-a-million,

Mr. Greg.
