diff src/core/ngx_file.c @ 493:975f62e77f02 release-0.1.21
nginx-0.1.21-RELEASE import
*) Bugfix: the ngx_http_stub_status_module showed incorrect statistics
if "rtsig" method was used or if several worker process ran on SMP.
*) Bugfix: nginx could not be built by the icc compiler on Linux or if
the zlib-1.2.x library was building from sources.
*) Bugfix: nginx could not be built on NetBSD 2.0.
