But some 70 lines after that "all:", a tab-at-beginning-of-line
appears, before the declaration of the next target. It appears as
follow :
CXX_FOR_TARGET_FLAG_TO_PASS = \
[TAB CHARACTER HERE] "CXX_FOR_TARGET=$(CXX_FOR_TARGET)"
# CXX_FOR_TARGET is tricky to get right for target libs that require a
# functional C++ compiler. When we recurse, if we expand
In that situation, this tab does not indicate a recipe then ?

variable assignment syntax.
Sure, but the thing I wanted to know is whether the command inside the
backticks gets executed when the variable is assigned, or not ? It
would be in
shell syntax. In makefile syntax I don't know
