Hello world,
the attached patch, tested with "tidy -e", puts the two parts
mentioning UNSSIGNED into a single paragraph, mentions
extensions to -fc-prototypes and mentions -Wexternal-interface-mismatch.
Comments, suggestions for better wording?
If not, I'll probably commit tomorrow.
Best regards
Thomas
