compile failure with newer gcc
I moved the repor to GitHub. SF Git browser has too many bugs and I have other projects at GitHub. https://github.com/set-soft/tvision Last release is 2.2.3 and compiles with gcc 10.2
Merge branch 'r2_0_1u' into master
Temporally disabled some options.
Partial suppor for CLang under MaxOSX
Fixed gcc 10.2.0 compilation errors.
Added unsigned abs version, seems to be needed by gcc-7
Updated the change.log
