conflict between url.sty and html.sty (with pdfetex)?

I've noticed that some documents that compile without problems
under the version of LaTeX I've been using don't compile under
a newer version. Before I start trying to plow through .sty
files, perhaps someone here will recognize this as a familiar
problem and suggest a fix or workaround ....

Here's a short example of such a document:

\documentclass{article}
\usepackage{url}
\usepackage{html}
\urldef{\BaseURL}\url{http://something.edu/}
\begin{document}
\noindent
Here is a formatted URL: \url{http://something.edu/~username}.
\end{document}

Under the "old" version of LaTeX, this compiles without problems.
Under the "new" version, I get the following error message:

! Undefined control sequence.
\pdfmark@ ...e \space pdfmark}\else \Hy@colorlink
{\@ifundefined {@\pdf@link...
l.4 \urldef{\BaseURL}\url{http://something.edu/}

If I comment out \usepackage{html.sty}, it again compiles okay under
both versions. If I comment out the \urldef line, again no problems.

"latex --version" for the "old" version reports

TeX (Web2C 7.3.1) 3.14159
kpathsea version 3.3.1

"latex --version" for the "new" version reports

pdfeTeX 3.141592-1.21a-2.2 (Web2C 7.5.4)
kpathsea version 3.5.4

I notice that url.sty has changed between versions, and that while
html.sty doesn't seem to have done so, hyperref.sty (which is pulled
in by html.sty) has also changed.

Anyone recognize this one?

html.sty uses a wrong "if pdf" test that no longer works now that also
for dvi-output ("LaTeX") the pdfeTeX-engine is used. The author should
use ifpdf.sty instead.

I'm not following you. Do you mean that the author of the documents
that don't compile any more (me) should replace html.sty with ifpdf.sty,
or that the author of html.sty should make this change (in html.sty)?

A change in html.sty.

And since html.sty appears to be part of latex2html, which hasn't been
updated (as far as I know) in a while, it's not clear the author ....

Well, I waded into html.sty and made the changes that seemed indicated
by Ulrike's comments (replacing all the tests for pdf-something to
use \ifpdf), and with the revised html.sty, I can generate PostScript
and (with latex2html) HTML. No idea what happens if I try to generate
PDF directly, but at least this solves my immediate problem. (Given
that most of what's in html.sty is beyond my knowledge of TeX, the
fact that the revision seems to work is somewhat surprising.)

So -- thanks! (Anyone know if (1) there's an official patch somewhere,
or (2) if not, if anyone would be interested in my revision?)

the latex2html maintainer knows about this problem (though it's not
clear to me that he quite understands its severity). it's been
discussed on the l2h list.

more complaints on the list (i've already contributed ;-) wouldn't
come amiss, i reckon...
