Do I need to take any action, e.g. do you want configure to check for these?
Are you trying to use the spec file and do you want it to enforce those
versions, or is this information just for the README?

For AIX < 5.2, it should be using fabs, not fabsf. The macro causes the
fabsf call to be redirected to fabs
-lm will definitely be in the next snapshot I give you - is this needed
for all AIX versions or just some versions?
I was looking at a document that told me _AIX52 would be defined on all
versions >= 5.2 - do you believe that is correct, or is it only defined
on that exact version?

I had already applied that on the branch, but to make the code portable
between AIX and other platforms, I did this by setting
EXPORT_SYMBOLS_DYNAMIC in configure.in and using it's value in
gmond/Makefile.am
Can you please look at whether EXPORT_SYMBOLS_DYNAMIC is being used
properly? Please share the output of this command:
egrep 'DYN|STATIC' config.status

I want to avoid patching aclocal.m4 and try to find the right way to
make this work
Looking at the comments in the code, do you know about the -brtl
suggestion? Can you try that flag in your LDFLAGS?
Could you also post this particular issue on the list autom...@gnu.org?
Someone else may already know the solution straight away.
