bug#24824: 26.0.50; error in process filter: Symbol’s function definition is void: mm-decode-coding-region

[Jean Louis]

Since I installed last w3 version 4.0.49, I am getting this problem:

error in process filter: Symbol’s function definition is void: mm-decode-coding-region

Right, the version of w3 you've installed is too old to work on the
version of Emacs you're using.  The function `mm-decode-coding-region'
doesn't exist any more.

To work around this, you could say

(fset 'mm-decode-coding-region 'decode-coding-region)

but this is not a bug in Emacs, so I'm closing this bug report.
