Check last line with gawk?

I am writing a gawk script that checks some basic code conformance rules (java text files) using gawk. So far, so good.

But I have a requirement to ensure that the last line in the java source files is "/* eof */". The below snippet works BUT is called more than once per file as / / matches a "few" too many expressions. So how do I perform this check only once???
...
/ /{
if ( tail -1 FILENAME ~ "/* eof */" ) {
print "Yeah"
}
}
...

Go easy, I'm a newbie.

Or can I do something like:

/\/\* eof \*\// {
if (Check if last line of file)
{
print FILENAME ": yay woot foo" > "/dev/stderr"
}
else
{
print FILENAME ": failed" > "/dev/stderr"
}
}

So how do I "Check if last line of file"?

Thanks for the idea,

Now how do I get it to work?

...
END{
theEOFComment = tail -1 FILENAME
print theEOFComment
if (match(theEOFComment, /eof/)) {
print "Yeah"
}

...
}
