I'm kind of confused about this. Two bugs were filed against my packages, both lib*-dev packages, i.e., development libraries. The only reverse depends on them are also lib*-dev packages. If there is an incompatible change in them, can't dependencies just be versioned so that all dependencies are on libraries built with glibc-2.5 and gcc-4.1.2 or above? This doesn't seem to be any different than introducing a new version of a shared library and the corresponding development package - the shared library changes version so packages can be partially upgraded, but the corresponding development packages don't. BTW, the only reference to long double is in config.h for each library, i.e.: $ egrep -i 'long.*double' /usr/include/Open*/* /usr/include/OpenJade/config.h:/* Define if you have the 'long double' type. */ /usr/include/OpenJade/config.h:#define HAVE_LONG_DOUBLE 1 /usr/include/OpenSP/config.h:/* Define if you have the 'long double' type. */ /usr/include/OpenSP/config.h:#define HAVE_LONG_DOUBLE 1 Please let me know what you think.
