# Cabal deletes project source files during configure The function in removes header files from the source directory when a header with the same name exists in both the build directory and the source directory. This behavior was introduced in commit to resolve header precedence issues, as C compilers prefer relative includes over search paths. The workaround uses on source directory files, which is destructive and should not happen during a build process. While the current implementation does not follow symlinks explicitly, the deletion of source files outside of the project during a build operation is possible on Microsoft Windows.
