Hello Hector,
it seems the package "libgcc1-arm-cross_4.1.1-21_all.deb"
is missing from the website. In fact, after clicking on the download link,
appears always the following message:
The requested URL was not found on this server. The link on the ">referring
page seems to be wrong or outdated. Please inform the author of ">that page
about the error. If you entered the URL manually please check your spelling
and try again.
I'm not sure about who is the author of that page but I think you could be
the best candidate to who address the problem.
