These headers are not used that often, and some of the functions are grossly under-specified, but at least it type-checks. That said, these headers (as most advanced ACSL specification) are primarily intended for use with WP or Jessie. For Value Analysis, you might have better luck by adding on the command line the corresponding .c implementations. In particular, with the string.c implementation: frama-c-gui -cpp-extra-args="-I`frama-c -print-path`/libc" -val file.c `frama-c -print-path`/libc/string.c the call to printf is not seen as dead.
