Subject: Update: Improve define structure, wrapping global static data in individual ifndef... 
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=d326c1159cadec156cbe87872662ffe0ea11508a;p=fll

Update: Improve define structure, wrapping global static data in individual ifndef blocks.

Make the example "build/disable" defines scripts more precise to avoid getting defines used from other projects from being loaded in the wrong file.

Use per variable wrapping ifndef defines to have better fine-tuned control over the compiled code.

Fix any problems observed with syntax and naming.
