Subject: Update: Improve thread configuration, document modes in build settings files, and... 
X-Git-Tag: 0.6.5~17
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=135b3c4ead9b7f3867d1ce23069d4d3b3da8a827;p=fll

Update: Improve thread configuration, document modes in build settings files, and update build scripts.

Improve the thread configuration to make it easier to enable or disable thread support.

Add documentation regarding the build modes supported in each of the build settings files.

Update the build scripts to better handle the now additional build modes.
The build scripts now use braces everywhere.
Doing this should make it easier to be compatible with other scripting engines such as ZSH.
