+
+# Note that the output of uname -m is probably not what Philip expected,
+# so you might end up with more build-AIX-random_number directories than
+# you expected if you have too many AIX boxes, but it seems to work... I
+# blame IBM.
+
+# Note that nowadays you have to pay extra for a cc compiler with AIX!
+
+CC=gcc
+
+# This needs to be in here rather than os.h-AIX because of regexp stuff.
+# basically strchr is a #define, which means "extern char *strchr()"
+# ruins things. __STR31__ seems to get around this by magic. The AIX
+# include files are quite a confusing maze.
+# Mike M says this is not necessary any more; possibly this is related to
+# using gcc. Commented out by PH.

+Files in this directory are historical. They may have worked once but the

+
+If you need to use one for a build for your platform, copy it up one directory
+level first. We'll reinstate it given a current version and evidence of testing.
+For the latter please look into the project regression testsuite, and please
+consider operating a buildfarm animal in the long term (it runs the testsuite).
+
+The buildfarm status page is:
+ https://buildfarm.exim.org/cgi-bin/show_status.pl
+There's a "register" link there with a link to how-to instructions. Please do
+monitor the status of your animal on an ongoing basis. The exim-users or
+exim-dev mailinglist are good places to ask for help and to discuss any regressions
+seen in test runs. There is also the #exim IRC channel on Freenode.
