Another approach is to let gcc do the parse for you, then load the result.
You can do this by running gcc on the source files with -fdump-translation-unit option. GCC::TranslationUnit can then be used to examine the parse tree.
From the GCC::TranslationUnit doco:
use GCC::TranslationUnit;
# echo '#include <stdio.h>' > stdio.c
# gcc -fdump-translation-unit -c stdio.c
$node = GCC::TranslationUnit::Parser->parsefile('stdio.c.tu')->root;
# list every function/variable name
while($node) {
if($node->isa('GCC::Node::function_decl') or
$node->isa('GCC::Node::var_decl')) {
printf "%s declared in %s\n",
$node->name->identifier, $node->source;
}
} continue {
$node = $node->chain;
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
