I'm a little puzzled why this change was needed. The configure script
takes each compiler flag in turn & attempts to compile a test program.
If this test fails it doesn't use the flag for main libvirt build. Any
ideas why the configure test succeeeded, but libvirt build didn't ?
I tried two different gcc's from Debian. The errors were:
hidden symbol `__stack_chk_fail_local' in [...] is referenced by DSO
/usr/bin/ld: final link failed: Nonrepresentable section on output
and even wierder:
/usr/lib/libc_nonshared.a(elf-init.oS)(.gnu.linkonce.t.__i686.get_pc_thunk.bx+0x0):
In function `__i686.get_pc_thunk.bx': multiple definition of
`__i686.get_pc_thunk.bx'
