[boost] svn pre-commit problem and long file names

I am trying to submit a copy of the GIL documentation into main. The documentation consists of hundreds of files auto-generated by Doxygen. Many of them have longer names than 31 characters, and the svn pre-commit hook fails because of that. I couldn't figure a way to make Doxygen generate smaller file names and it would be impossible to manually shorten the names of hundreds of files every time we need to generate the files. Can we lift the file name length restriction? Any other solutions? Thanks, Lubomir
