Re: Successfully compiled 1.3.1 on AIX 5.2 /w Visual Age C++ 6.0 after some tweaking

[David Sugar]

The question I see is how this could be applied to the more general case 
of the distribution itself.  The HAVE_SYS_LIBCSYS_H, or inclusion of the 
associated include file could possibily be contained through a _AIX_ 
macro test, if a reliable "_AIX_" type define exists.  For example, we 
could change:

#ifdef HAVE_SYS_LIBCSYS_H
#include <sys/libcsys.h>
#endif

to a #if defined(HAVE_SYS_LIBCSYS_H) && !define(_AIX_..)

assuming a suitable define to test for can be suggested.

I wonder what we can do for dynamic_casts and rtti, though.  Of course I 
prefer not to use C++ exceptions, and none of my newest apps or libs 
based off Common C++ depend on exception handling.

As for problems in libtool, that is a question for the libtool maintainer.

#pragma pack(nopack) could also be handled by the same _AIX_... specific 
define.

We could possibily add additional compiler flag tests for aix targets 
through the "$target_os" case tests we already have in configure.ac. 
Perhaps we could also reverse the default for  --without-exceptions for 
aix under such a test.

I am curious if ccrtp and ccaudio2 also successfully build on AIX, and 
if dynamic loading of plugin components work correctly.
