No. The relevant part of the code reads:

if (i % (hashRounds / 16) == 0)
{
NSha1::CContext shaTemp = sha;
Byte digest[NSha1::kDigestSize];
shaTemp.Final(digest);
aesInit[i / (hashRounds / 16)] = (Byte)digest[4 * 4 + 3];
}

You complete a copy of the hash, shaTemp.Final(), and then extract one
byte into the IV. This is repeated 15 more times at regular intervals
through the hashing process.
Is this C oder C++?

It is C++ as far as I can tell. The "::" element is not legal C, at
least it wasn't when I last worked in C a very long time ago.

The Pascal equivalent is ".": NSha1.Context or NSha1.kDigestSize
referring to the NSha1 class.
