[SOLVED] Use another char than # in preprocessor directives

Issue

Is there a way to use another char than # when defining preprocessor directives? Example:

Instead of:

#if 1
foo
#endif

Use ?, for example:

?if 1
foo
?endif

Solution

There are trigraph sequences that exists to replace certain characters. In particular, the # character can be replaced with ??=. So the following code is valid:

??=if 1
foo
??=endif

You can't however put an arbitrary replacement in place.
