Bug #: 13741
Summary: Compilation fail with g++ 3.3.6 with option
-ffast-math due to undefined macros
__extern_always_inline
Product: glibc
Version: 2.15
Status: NEW
Severity: minor
Priority: P2
Component: math
AssignedTo: unassigned@sourceware.org
ReportedBy: uleysky@gmail.com
CC: aj@suse.de
Classification: Unclassified
Very simple testcase test.cpp
#include <math.h>
int main() { return 0; }
g++-3.3.6 -o t -ffast-math test.cpp
In file included from /usr/include/math.h:424,
from test.cpp:1:

/usr/include/bits/math-finite.h:325: error: `__local_signgam' was not declared
in this scope
/usr/include/bits/math-finite.h:326: error: syntax error before `return'
The root of problem is simple: in this case macros __extern_always_inline not
defined. Also, the problem is observed only with g++, not gcc.

Please use newer version of g++. The 3.3.6 version is now deprecated.

Actually that is not the case. GCC 3.3.6 isn't supported for building of glibc
itself, still, compiling with GCC 3.3.6 your own programs against glibc headers
and linking against it is supported.

Conditioning these definitions on __extern_always_inline being defined is
probably the appropriate fix.
