All reports of bad-permissions-for-ali-file for the archive. The extended description of this tag is:
Ada Library Information (*.ali) files are required to be read-only (mode 0444) by GNAT.
If at least one user can write the *.ali file, GNAT considers whether or not to recompile the corresponding source file. Such recompilation would fail because normal users don't have write permission on the files. Moreover, such recompilation would defeat the purpose of library packages, which provide *.a and *.so libraries to link against).
Refer to Debian Policy Manual section 8.4 (Development files) for details.
