[PATCH 08/52] ACPICA: iASL: Improved pathname support

Len Brown
2012-07-25T03:42:20Z

From: Bob Moore <robert.moore@intel.com>

For include files, merge the prefix pathname with the file
pathname. Convert backslashes in all pathnames to forward
slashes, for readability. Include file pathname changes affect
both #include and Include() type operators.
