This would have detected the bug in commit 38ad33931 (Aug 09), which we missed until commit f828ca35 (Jul 10); over 11 months later. However, on Fedora 13, it also triggers LOTS of warnings from the libcurl-devel header for two files: esx/esx_vi.c: In function 'esxVI_CURL_Perform': esx/esx_vi.c:232: error: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op] esx/esx_vi.c:232: error: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op] esx/esx_vi.c:232: error: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op] ... xenapi/xenapi_driver.c: In function 'call_func': xenapi/xenapi_driver.c:1872: error: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op] xenapi/xenapi_driver.c:1872: error: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op] xenapi/xenapi_driver.c:1872: error: logical '&&' with non-zero constant will always evaluate as true [-Wlogical-op] ... libcurl allows to disable the type-checking code that triggers those warnings, along with the reduction in type-safety of calls to some libcurl functions. I figure this is worth the improved compiler checking throughout the rest of libvirt. * acinclude.m4 (--enable-compile-warnings=error): Add -Wlogical-op. * configure.ac: Add -DCURL_DISABLE_TYPECHECK to LIBCURL_CFLAGS to avoid compilation warning.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
