When I try to compile parhello-libev.c with clang -Weverything, it prints a spurious warning about recursive macros.
Source: https://github.com/mcandre/parhello/tree/master/c/parhello-libev Trace: $ make clang -O2 -Wall -Wextra -Wmost -Weverything -o parhello parhello.c -lev parhello.c:17:16: warning: disabled expansion of recursive macro [-Wdisabled-macro-expansion] putc(data, stdout); ^ /usr/include/stdio.h:173:16: note: expanded from macro 'stdout' #define stdout stdout ^ /usr/include/stdio.h:585:39: note: expanded from macro 'putc' #define putc(_ch, _fp) _IO_putc (_ch, _fp) System: $ specs clang os Specs: specs 0.8 https://github.com/mcandre/specs#readme clang --version Ubuntu clang version 3.4-1ubuntu3 (tags/RELEASE_34/final) (based on LLVM 3.4) Target: x86_64-pc-linux-gnu Thread model: posix lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04.1 LTS Release: 14.04 Codename: trusty This oddity was noted some time ago ( http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20130128/073127.html). Any update on this behavior? -- Cheers, Andrew Pennebaker www.yellosoft.us
