ACPICA commit e2df7455a9a4301b03668e4c9c02c7a564cc841c Some hosts may choose not to include stdarg.h, implementing a configurability in acgcc.h, allowing OSen like Solaris to exclude stdarg.h. This patch also fixes acintel.h accordingly without providing builtin support as Intel compiler is similar as GCC. Reported by Dana Myers, fixed by Lv Zheng.
