Curl not included in -I flag

[nmail_uk]

I've got an issue with the 1.8 configure script that has been an issue since 1.6.2. When the cURL library is installed in a non-standard location, it's path is not included in the compiler's -I flag, thus creating errors during make.

My curl is installed under /opt/nmail32/curl, so the flag "-I/opt/nmail32/curl/include" should be added to the compiler's flags.

I think it's also not doing the same with the OpenSSL and zlib libraries, although the library paths must have been picked up from somewhere else as I didn't specify them in my configure line.

The script sets the linking flag correctly, as shown below.

CFLAGS="-m32" LDFLAGS="-m32" ./configure --prefix=/opt/nmail32/zabbix --with-pgsql=/opt/nmail32/pgsql/bin/pg_config --with-libcurl=/opt/nmail32/curl/bin/curl-config --enable-server --enable-proxy --enable-agent
