Hi All,

Is the EmbeddedPkg being actively developed by the Tianocore / edk2 community?

I saw following Warnings & errors while trying to build it.

Want to check with the community leaders if it is worth investing time in raising BZ and fixing these errors / warnings?

Please find the details of the errors / warnings as given below:


1)
SyntaxWarning: invalid escape sequence '\C'

This warning message is seen with the latest edk2 code available in the main branch.
part of the build logs are copied over here for reference.
