Hello,

On an AIX 5.3 (5300-07-03-0811), I have trouble compiling the "neon"
WebDAV client library with SSL support.

I've installed the OpenSSL package from IBM's "AIX Web Download Pack
Programs" page (openssl.9.8.410.tar.Z).

And I've installed gcc, m4, automake, libtool, etc from IBM's "AIX
Toolbox for Linux Applications".

After having extracted the neon-0.28.2 sources, I run:
../configure --with-ssl

After a while, configure responds with:
....
checking openssl/ssl.h usability... no
checking openssl/ssl.h presence... no
checking for openssl/ssl.h... no
configure: error: OpenSSL headers not found, cannot enable SSL support

From config.log:
| #include <openssl/ssl.h>
configure:28050: result: no
configure:28054: checking openssl/ssl.h presence
configure:28069: gcc -E -D_LARGEFILE64_SOURCE -DNE_LFS conftest.c
In file included from /usr/include/openssl/ssl3.h:142,

Does this make sense to anyone?

Yes. Check inside pq_compat.h

It turns out that IBM's openssl package contains a number of include
files in /usr/include/openssl where a special "IBM prolog" has been
added, making them incompatible with gcc:

# IBM_PROLOG_BEGIN_TAG
# This is an automatically generated prolog.
[...]

After having removed these headers, neon compiles.

Sigh.
