Sorry. I'll add this to the zip file soon.

Thanks!  Yes. It is a package conflict !  I am trying now to make
a MWE to show this. It is in one of these 2 files that I subimport.

Now for the issue of subimport. It does with with tex4ht. I use
standalone package and subimport very heavily in all my documents.

I forgot to mention that one needs a patched standalone package
to make it work with tex4ht. It is a long story. But Martin Scharrer
was kind enough to patch the standalone package to make it work
with tex4ht few years ago. It is not yet in the main TL 2015 tree.

So each time I make new TL, I download the patch and replace
the current standalone.sty with the patched one.

https://bitbucket.org/martin_scharrer/standalone/raw/635aacfa0e8f2cba4f4086f4f15d57791b18bf64/standalone.sty

I'll add this to the zip file also so it is all self contained.

Here is the related question on tex stackexchange with Martin explaining
the issue in the comment.

http://tex.stackexchange.com/questions/95701/syntax-error-when-using-tex4ht-on-latex-file-that-uses-the-standalone-package

Again, standalone and subimport work with tex4ht. But one needs to use
the above .sty file, not the one that comes with TL 2015.

I am trying now to find which package loading is causing the
conflict. I narrowed down the latex file to only this:

-----------------------------------------------
\documentclass[12pt,notitlepage]{report}%
\input{commonlatex}
\usepackage{standalone}
\usepackage{import}
\begin{document}
\subimport{problems/e97/}{e97}
\subimport{problems/e98/}{e98} % in here seems to be the problem
\end{document}
-------------------------------------------

And the above causes the error code to show.

I will update the mailing list once I find where the conflict is
and make new zip file.  We are getting close!
