#30 LPC2000: Fix for "Error: invalid literal constant: pool need

[Oliver]

Under some circumstance the compiler generates an error "Error: invalid literal constant: pool needs to be closer". This happens when the code size exceeds a certain amount so that the compiler can't load for example ulCriticalNesting directly. The attached file contains my patches. I use them now for 2 years without known problem.

Fixed macros portSAVE_CONTEXT and portRESTORE_CONTEXT

This is for a very old vesion of code and I think was fixed.
