It seems that not just GCC flags this a possible error, in the Java audit rules
in some Google Software this problem is named "Dangling Else":

http://code.google.com/intl/en-EN/webtoolkit/tools/codepro/doc/features/audit/audit_rules_com.instantiations.assist.eclipse.auditGroup.possibleErrors.html#com.instantiations.assist.eclipse.audit.danglingElse


It says:
This audit rule finds places in the code where else clauses are not preceded by
a block because these can lead to dangling else errors.

Example
    if (a > 0)
        if (a > 100)
            b = a - 100;
    else
        b = -a;
