A small remark: 'diff A B' works OK, but 'diff -u A B' does not. Adding --color does not change anything.

"diff -ud A B" brings only *one* 'program error' plus a "+Abort" message (Exit 134):

The last two lines are green. "diff: program error" and "compiler.cxx_standard \\              2011" are in terminal text colour. Leaving '--minimal' away produces:

Anyway, I am going backwards!
