New versions of icc confuse auto/cc/name due to introduced handling
of a "icc -v":
$ icc -v
icc version 12.1.3 (gcc version 4.6.0 compatibility)
$ icc -V

At least Sun Studio 12 has problems with bit-fields exposed by nginx code
(caught by test suite). They seems to be fixed in Sun Studio 12.1. As a
workaround use "-fast -xalias_level=any" for older versions, it resolves
the problem.
*) Change in internal API: the HTTP modules initialization was moved
from the init module phase to the HTTP postconfiguration phase.
*) Change: now the request body is not read beforehand for the
ngx_http_perl_module: it's required to start the reading using the
$r->has_request_body method.
*) Feature: the ngx_http_perl_module supports the DECLINED return code.
*) Feature: the ngx_http_dav_module supports the incoming "Date" header
line for the PUT method.
*) Feature: the "ssi" directive is available inside the "if" block.
*) Bugfix: a segmentation fault occurred if there was an "index"
directive with variables and the first index name was without
variables; the bug had appeared in 0.1.29.
*) Change: now the ngx_http_charset_module works for subrequests, if
the response has no "Content-Type" header line.
*) Bugfix: if the "proxy_pass" directive has no URI part, then the
"proxy_redirect default" directive add the unnecessary slash in
start of the rewritten redirect.
*) Bugfix: the internal redirect always transform client's HTTP method
to GET, now the transformation is made for the "X-Accel-Redirect"
redirects only and if the method is not HEAD; the bug had appeared
in 0.3.42.
*) Bugfix: the ngx_http_perl_module could not be built, if the perl was
built with the threads support; the bug had appeared in 0.3.46.
