Bug#503202: libc6-dev: math_errhandling isn't defined anywhere
Package: libc6-dev Version: 2.3.6.ds1-13etch7 Severity: important Hi, math.h has the following in it: /* Bitmasks for the math_errhandling macro. */ # define MATH_ERRNO 1 /* errno set by math functions. */ # define MATH_ERREXCEPT 2 /* Exceptions raised by math functions. */ but no-where is math_errhandling actually defined! This breaks code wanting to check how domain errors in floating-point code are handled (amongst other things). Section 7.12.9 of C99 discusses MATH_ERRNO, MATH_ERREXCEPT, and math_errhandling. SuSv3 also requires math_errhandling to be present: http://www.opengroup.org/onlinepubs/009695399/basedefs/math.h.html Regards, Matthew -- System Information: Debian Release: 4.0 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.20-2-macpro-amd64 Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Versions of packages libc6-dev depends on: ii libc6 2.3.6.ds1-13etch7 GNU C Library: Shared libraries ii linux-kernel-headers 2.6.18-7 Linux Kernel Headers for developme Versions of packages libc6-dev recommends: ii gcc [c-compiler] 4:4.1.1-15 The GNU C compiler ii gcc-3.4 [c-compiler] 3.4.6-5The GNU C compiler ii gcc-4.1 [c-compiler] 4.1.1-21 The GNU C compiler -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

See the footnotes on http://gcc.gnu.org/c99status.html . Reassigning the bug accordingly. gcc on Mac OS X gets this right (the libc there defines math_errhandling), which is why I suspected glibc to be the problem. I infer from that, that glibc could fix this without needing changes to gcc? Matthew -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

The behaviour of the macro has to be different if for example -ffast-math is used, but also because some math functions are provided by gcc. -- .''`.
