I'm trying to fix the appveyor setup for Boost.GIL, where I need to create a 
`user-config.jam` file with entries for third-party libraries libjpeg, libpng,

and here is the error this results in:

https://ci.appveyor.com/project/stefanseefeld/gil/build/1.0.109-develop/job/n6yco00602f8pqn7#L974

I'm sure I'm not the first one to attempt to do this (i.e., create a custom 
user-config.jam on appveyor). Can someone see what I'm doing wrong ?

  This looks like a permissions issue.

It doesn't appear to be one. This fails: https://ci.appveyor.com/project/stefanseefeld/gil/build/1.0.114-bug/job/c2ssclb178o24hfl
while this works: https://ci.appveyor.com/project/stefanseefeld/gil/build/1.0.113-bug/job/g82xoju5fpv52gxe

So the error seems related to the use of the %CHUNK% variable, which is defined as

set "CHUNK=^<include^>%VCPKG%\include ^<search^>%VCPKG%\lib"

(I can't claim I understand the syntax. https://stackoverflow.com/questions/47679060/permission-issue-with-simple-appveyor-script suggests I need to quote the entire assignment rather than just the right-side hand, to avoid the quotation marks to be included in the variable. And I need the '^' to prevent cmd.exe from interpreting the '>' character in the value...)

This is why I had hoped that someone else had already generated user-config.jam files in appveyor.yml files, so I could simply learn from that experience, rather than stumbling around in the dark as I do now.

Thanks,
