[Bayonne-devel] Re: Issue with running make on AIX 5.2

[David Sugar]

The THREADSAFE macro is defined as a compiler flag because we currently
use the config.h file generated from autoconf/automake in target
applications as the "root" or first include header from other headers
Common C++, and this may have other includes embedded in it.  We have to
have _THREAD_SAFE defined for any libc headers before they are included....

In AIX, standards.h defines _THREAD_SAFE as a means of resolving this
same kind of issue, I assume.  You can strip it from the compiler
CXXFLAGS.  I had resolved this issue by eliminating the use of the
generated config.h when I originally refactored Common C++ late last
year, but the results of that effort have not yet been released, and in
any case actually became a new library and a new way of programming C++.

I would like to see if we can do a simple solution in Common C++,
perhaps just using the configure.ac case for target type to exclude the
_THREADSAFE define if the target platform is AIX.
