Re: [Chicken-users] Optimal C

[Rick R]

Ahh, I was going overboard by including the crunch macro while using
chicken-crunch.
When I use one technique or the other, the .cpp's are created fine,
however it results in this error from gcc:

/usr/local/include/crunch.h:420: error: explicit template
specialization cannot have a storage class
/usr/local/include/crunch.h:421: error: explicit template
specialization cannot have a storage class
/usr/local/include/crunch.h:788: error: explicit template
specialization cannot have a storage class

In all three cases, the function signature is template<> .
I'm not sure if this is intended.
