How come? If you are building stage 4.2 (libraries), you have already =
built cross-tools, so the "cc" invoked above only uses headers from =
${WORLDTMP}.
The -I options you show only point to either your source directory, or =
your object directory:
-I/usr/home/luigi/FreeBSD/head/crypto/openssl
-I/usr/home/luigi/FreeBSD/head/crypto/openssl/crypto
=
-I/usr/home/luigi/FreeBSD/obj_head/usr/home/luigi/FreeBSD/head/secure/lib/=
libcrypto
-I/usr/home/luigi/FreeBSD/head/crypto/openssl/crypto/asn1
-I/usr/home/luigi/FreeBSD/head/crypto/openssl/crypto/evp
-I/usr/home/luigi/FreeBSD/head/crypto/openssl/crypto/modes

No idea, sorry. I have never seen this problem. I have even built very =
recent head on 8.1-RELEASE and 7.3-RELEASE, with a few minor patches...
