[CM] Bug in cload init function generation

[bil at ccrma.Stanford.EDU]

Thanks for the bug report.  cload is assuming there is at least
one function, so to fix that I think you can just change
line 501:

501c501,502
< 	(format p "  s7_pointer ")
---
> 	(when (> (hash-table-entries signatures) 0)
> 	  (format p "  s7_pointer "))
