[bug #59956] Recipes inside conditionals can break the parser

[anonymous]

Follow-up Comment #5, bug #59956 (project make):

> We can "fix" it by adding a simplifying heuristic; perhaps something like:
"conditional statements are only recognized if they are not prefixed by the
recipe prefix in effect when the if-statement started".  That is not perfect
but it's probably good enough.

I think this heuristic as stated would be disastrous at my $dayjob and
probably many others. Almost everyone who works on makefiles here is a C
programmer by trade and they're accustomed to indenting by tabs so I see a lot
of:

if ...
<tab>if ...
<tab>else
<tab>endif
else
endif

I try to discourage this and have written up a style guide which includes
"tabs should be used only as a recipe prefix" but there are still many such
instances.
