This is not right. In several libraries (e.g. GNU libunistring), the config.h header does #define realloc someprefix_realloc and later (with the help of libtool or of the 'lib-symbol-visibility' module) the symbols someprefix_* are unexported from the shared library being created. The patch above has the effect that libunistring.so will now export 'realloc'. Which is not right. The comment above that line references the AC_FUNC_REALLOC macro. I doubt there are many packages that still use AC_FUNC_REALLOC the "old" way, without gnulib. (Maybe gawk still does?) Bruno
