Can't build 1.1.5 on Solaris-like system

[Neddy Hai Nam]

I'm running 1.1.4 as well and was trying to build 1.1.5 on testing server, the running system is OpenIndiana 151a2 32-bit, GCC 4.6.2, build conditions:

# ./configure --prefix=/usr/nginx --without-http_autoindex_module --without-http_geo_module --without-http_map_module --without-http_uwsgi_module --without-http_scgi_module --without-mail_pop3_module --without-mail_imap_module --without-mail_smtp_module

# make

Ack, it looks like Solaris defines AT_FDCWD as unsigned:

#define        AT_FDCWD                        0xffd19553

and this causes warnings on compare with file descriptors (which use signed int type) with modern versions of gcc. Will be fixed shortly. As a workaround you may use

./configure --with-cc-opt="-Wno-error=sign-compare"

for now.
