I know that constants used within functions could be done via atstart() mechanism or on first function call; but as these lengths are already constants in the assembler output, any strlen() overloading wouldn't work anyway. So, as conclusion: If strlen() is taken as known for constant strings (and optimized as such), no warning about its return value being non-constant should be given. Or am I missing some part of the picture? -- System Information: Debian Release: lenny/sid APT prefers testing APT policy: (600, 'testing'), (50, 'unstable'), (1, 'experimental') Architecture: i386 (i686) Kernel: Linux 2.6.22-1-686 (SMP w/1 CPU core) Locale: LANG=de_AT.UTF-8, LC_CTYPE=de_AT.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to de_AT.utf8) Shell: /bin/sh linked to /bin/bash Versions of packages gcc-4.2 depends on: ii binutils 2.18.1~cvs20080103-3 The GNU assembler, linker and bina ii cpp-4.2 4.2.3-3 The GNU C preprocessor ii gcc-4.2-base 4.2.3-3 The GNU Compiler Collection (base ii libc6 2.7-10 GNU C Library: Shared libraries ii libgcc1 1:4.3.0-3 GCC support library Versions of packages gcc-4.2 recommends: ii libc6-dev 2.7-10 GNU C Library: Development Librari -- no debconf information
