Comment #40 on issue 1815 by [email protected]: lilypond-book fails on Windows
http://code.google.com/p/lilypond/issues/detail?id=1815
Regarding comment 6, the difficulty was that the installer, NSIS, uses strings of length 1024 by default <http://nsis.sourceforge.net/Special_Builds> so it cannot hold a long PATH in a string variable. LilyPond's naïve installation script did not check for failure on reading the current PATH, but appended its own path to the empty string and wrote that. issue 1966
We would need someone motivated and able to help with the cross-platform build-and-install system, to write Windows PATHs in a safe way.
