Description

When I apply an hlint-suggestion to a piece of code where CPP is used somewhere else in the file, the expanded CPP is weirdly expanded.

Contributor guide

Research direction
Examine how HLint applies suggestions in files with CPP conditionals; trace the interaction between HLint's transformations and the C preprocessor to identify why CPP expansions become malformed.
