#2598 default library(s) not included? Missing delay implementations.

[James A. Cleland]

Link doesn't appear to include functions from delay.h.
Attempting to build using MPLABX. Simple command line make also attempted. Symbol is always missing.

Sorry for the terribly formatting, this is my first bug report.

[James A. Cleland]

Explicitly linking with libc18f.lib resolves external references to delay functions. I'm not sure if this is a bug or not, I don't see this library explicitly specified in the wiki examples so I'm assuming it should be linked by default for PIC18 devices. If not, then this is not a bug. Thanks!
