--- Begin Message ---Package: libc6.1-dev Version: 2.7-18lenny7 Severity: normal When compiling the file test.c containing: #include <math.h> double test(double x) { return round(x); } using gcc 4.2.4-6 on a DEC Alpha machine produces the following result: test.c In function `test': test.c:5: warning: incompatible implicit declaration of built-in function `round' Upon examining the output from the command (i.e., the file temp.tmp): gcc -E -o temp.tmp test.c There is no declaration of the `round' function yet, as far as I can determine, such a declaration should be present because it is in /usr/include/math.h via the include of /usr/include/bits/mathcalls.h. If I put an explicit declaration for `round' in test.c, no warning is reported. -- System Information: Debian Release: 5.0.8 APT prefers oldstable APT policy: (500, 'oldstable') Architecture: alpha Kernel: Linux 2.6.26-2-alpha-generic Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages libc6.1-dev depends on: ii libc6.1 2.7-18lenny7 GNU C Library: Shared libraries ii linux-libc-dev 2.6.26-26lenny2 Linux support headers for userspac Versions of packages libc6.1-dev recommends: ii gcc [c-compiler] 4:4.2.4-5 The GNU C compiler ii gcc-4.2 [c-compiler] 4.2.4-6 The GNU C compiler ii gcc-4.3 [c-compiler] 4.3.2-1.1 The GNU C compiler Versions of packages libc6.1-dev suggests: ii glibc-doc 2.7-18lenny7 GNU C Library: Documentation pn manpages-dev <none> (no description available) -- no debconf information

I'm not sure what would > cause it.) Agh. I can't read. The warning is saying "the implicit declaration int round(double d); is incompatible with GCC's built-in definition double round(double d); ". Which is true, so closing. Thanks for reporting.
