Welcome.  Please remember to keep the mailing list CC'd for posterity.

Not in this situation, because the variable is expanded in the context
of a recipe.  Hence the entire contents of the variable are passed to
the shell to be executed.

Ah!  Windows!  Anyway, that's expected because the recipe is sent to the
shell, and so the shell tries to run teh "ifndef" program.

I recommend you use a variable:

ifndef SKIPCOMMAND1
command1 = command1
endif

define TEX_RECIPE
    $(TOOL) ... args ...
    $(command1)
    $(TOOL) ... args ...
    command2
    command3
    $(TOOL) ... args ...
endef
