the lib (due to bug in gcc; see comment.) I would have run the testsuite to check if everything is still behaving, but unfortunately i cannot run the testsuite anymore: it just sits there and does nothing even with a pristine checkout and an old gcc. srcdir=/tmp/busybox/testsuite /tmp/busybox/testsuite/runtest PASS: Applet order FAIL: Common typos PASS: Obsolete function usage PASS: Obsolete function usage <spins, ^C> make[1]: *** [check] Interrupt make: *** [check] Interrupt I've just corrected that wrong double-printing. Anyway. with gcc-4.1-HEAD from earlier today, we now have for defconfig+ COMPILE_AT_ONCE: 880 -rwxr-xr-x 1 433 433 893476 Apr 28 21:41 busybox.oorig-4.0 860 -rwxr-xr-x 1 433 433 874560 Apr 28 21:36 busybox.oorig 844 -rwxr-xr-x 1 433 433 858752 Apr 28 21:49 busybox text data bss dec hex filename 879920 11568 1039148 1930636 1d758c busybox.oorig-4.0 862802 10192 1038796 1911790 1d2bee busybox.oorig 848066 9100 1037536 1894702 1ce92e busybox values for 4.0.2 just added for reference..
