d5ca542102 Changed use of compile #defines which start with a _ character to not do this since defined symbols starting with _ are reserved to local compiler/runtime implementations in the C language. This addresses issue #32 2013-03-12 11:07:58 -07:00

bc40f6abde Removed recently linked dependence of VHD support on Large File support. VHDs can be supported without large file support up to the limits a system without large file support (i.e. 2GB). Fixes issue #35 2013-03-05 12:15:29 -08:00

4ff56d6c15 Changed all internal #ifdef's which were conditional on __linux to be conditional on either __linux or __linux__. Some platforms (PPC) don't define __linux when gcc is invoked with -std=c99. 2013-02-20 21:57:02 -08:00

448ee4ad3c Fixed open issues on corrupt or inconsistent differencing disks to properly return error status. 
Fixed error paths to report errors when copying a differencing disk.
Fixed structure alignment issues to produce dynamic VHDs which are compatible with Windows 7's disk management.
Fixed performance optimization which attempted to optimize dynamic disk BAT updates as dynamic disks grew.
Added -O attach option for to override consistency checks for differencing disks which may have unexpected parent GUID or timestamp values.
