In C, statics are implicitly initialized to all-bits-zero. While I only know this offhand to be standards-required for static data declared at toplevel, there's no way under the Unix assembler/linker paradigm to specify that a non-stack variable is truly uninitialized. Adding a '= 0;' might be a style recommendation. However, in past people often avoided that due to lazy compilers that would then put the object in the data section, wasting space in the final executable file. I also understand at one point GCC was deliberately so stupid in order to accomodate a common hack to do what, today, we do with the "_edata" linker-generated symbol. Current GCC seems to be smart, though. ---- Michael Deutschmann <[email protected]> _______________________________________________ uClibc mailing list [email protected] http://lists.busybox.net/mailman/listinfo/uclibc
