The patch is against master. Are we supposed to make patches against master or maint? (I thought I saw the latter somewhere. I'm pretty new in here though..)

I can confirm that master doesn't compile on AIX 5.1 with the IBM VisualAge compiler V5 (V5.0.2) without the patch above, and it does compile with the patch:

Tested-by: Tor Arntsen <tor@xxxxxxxxxxx>

but with the following caveats:

1: With the patch, it'll build with configure (and only configure), run like so:

./configure --enable-pthreads=-lpthread CFLAGS=-Dinline=''

In other words, this system would also need an AIX version of the 'no-inline' patch you did for HP-UX.

And without the --enable-pthreads=-lpthread above it'll try to link with -pthread, which won't work for this system.

The const-expr patch is also useful for AIX-5.1 / XlC V5.0.2. It does build without, but with warnings.

2: The compiler cannot build on AIX 5.1 without the following additional patch (against master. maint has similar problems but files have been moved):
