It is much safer to make the symbols by default not exported. I'm currently working on merging most of the machine-dependent patches from our sources into gcc 4.1 - that's a 400 KB patch - and this will change most of the FUNC definitions in lib1funcs.asm to HIDDEN_FUNC, and all the ALIAS defintions into HIDDEN_ALIAS, and also change the way references to symbols in lib1funcs.asm are generated, so that for some symbols GOT references are made rather than PLT ones when compiling pic/PIC code. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20617
