Re: [Libvir] [PATCH 1/3] configure.in compiler and enable libtool DLLs

In this patch what I've done is to move the checks for C compiler and checks for programs apart from each other. We check for the C compiler first, then check for external programs later. This is just a cleanup. I've added AC_LIBTOOL_WIN32_DLL which enables DLL support in libtool (but shouldn't affect any other platform). I've added AM_PROG_CC_STDC which appears to be required by the above. I've added AC_C_CONST which is needed because libvirt uses 'const' without taking any special precautions for ancient compilers which don't support it.
