 Agreed, but I suspect there are higher priority issues than improving 
error callbacks for my use case. Changing this would require another 
tcc_set_error_func (bloat), or breaking existing users. I'm happy to 
code it though if it is seen as valuable long term.

Since I've now seen exactly how the error handling is generated, will 
just decode the error message string.
