Uh oh. The error message format gives no hint to
preview-latex about
the _column_ of the errors. This absolutely cannot be
fixed from within
preview-latex. Try to see whether you can configure your
pdftex to
produce a more TeX-like error message, or any other way
for the error
message to show the problematic column (the latter may
need further work
on preview-latex by the developers, but at least will move
the problem
from the state of "unfixable").
If you can do so using some command line option, that can
be configured
into AUCTeX's way of calling LaTeX, of course.
I see that your settings include
LaTeX-command-style '((""
"%(PDF)%(latex) %(file-line-error)
%(extraopts) %S%(PDFout)")
)
It would seem that the setting of %(file-line-error)
chosen for MikTeX
precludes correct column info. As a temporary measure, it
might work to
do
M-x customize-variable RET LaTeX-command-style RET
and then removing the %(file-line-error) part from the
customization
option.
