This really should be caught in configure where check_mathfunc log2 and
log2f generate implicit declaration of function warnings. One fix would
be enabling -Werror=implicit-function-declaration earlier in configure.
That fix you suggest is less trivial than it may sound.
What about the attached? OS/2 (actually eCS) is now shipping with GCC
4.5.2 which is plenty new enough to support
-Werror=implicit-function-declaration and it can be removed if and when
the headers are fixed.
I've filed http://svn.netlabs.org/libc/ticket/243 about this.
Can you paste config.log and config.h somewhere? And maybe upload a
tarball of system headers?
Sure, they should be here, http://www.box.net/shared/rm86u32ey0. Note
that there are a couple of headers that I've added such as pthread.h.
The headers are also available at
http://svn.netlabs.org/libc/browser/branches/libc-0.6/src/emx/include.
What libc does OS/2 use?
It's a fork of the ancient EMX libc
(http://en.wikipedia.org/wiki/EMX_%28programming_environment%29),
http://svn.netlabs.org/libc/wiki.
