Flex supports negated character classes, so you could do:

/* definition section */

%%

Signature[^)]*\) { /* custom code */ }

%%

/* user subroutines */

You can use following regex

\bSignature[\s\S]*?[)]

This regex will first look at Signature, followed by any character which includes alphanumeric characters, \n , etc followed by )

The problem is that . doesn't match new-lined by default.

A simple option is:

/signature[^)]*\)/i

[^)]* will match all characters besides ).

I'm not sure if you have a Dot-All flag in flex. In JavaScript the /s flag is missing, and the common work around is:

/signature[\s\S]*?\)/i

In this case, you probably want to use a lazy quantifier, *?, so you match until the first ), and not the last.
