Last I looked, standard c-library posix/gnu/perl/java
regex only worked on strings, not on binary data.
You'll have trouble finding a binary-data regex
implementation in C (or any other language).

No, this sounds somehow broken. If I remember correctly,
binary mime-parts should have a ConentLength header
so you can skip over them. If ContentLength is absent,
then the part should bee ascii-encoded (e.g. base64)
yeah, grapping large blocks of ascii sucks, which is
why the ContetnLength should be used.
