The following significant problems have been reported with this version of EPICS Base:

• 2015-05-01: The version detection code in the Cygwin-specific file src/libCom/osi/os/cygwin32/systemCallIntMech.cpp is wrong and breaks with the latest version of Cygwin. This patch fixes that problem.
• 2015-04-29: The latest version of Cygwin (using gcc 4.9.2) has moved the declaration of the select() system call to a different header file. This patch adjusts the Base headers so Base builds properly with the latest Cygwin.
• 2015-04-09: The dbContextReadNotifyCacheAllocator clears its pool of free buffers on an array size change, but doesn't consider buffers currently in use, which will later be free'd. Such buffers were being returned to the pool and later reused in allocations for which they were too short. This patch tracks the size of buffers which are in use and only returns buffers which are the correct length to the pool. Smaller buffers are free'd immediately.
• 2014-12-23: This patch fixes an error message from iocInit about forward-links over CA, thanks to Dirk Zimoch.
• 2014-12-11: Windows builds using the -j (parallel build) option may not work properly when SHARED_LIBRARIES = YES without first applying this patch to add a couple of missing dependency rules.
• 2014-12-11: Patch to remove a trailing ; from the definition of the macro dbGetSevr.
• 2014-12-04: To build for the 64-bit iPhone Simulator target you will need to apply this patch. The ARCH_CLASS setting in the new configure/os/CONFIG_SITE.Common.ios-x86 file controls which CPU architectures to include in the universal binaries generated.
• 2014-12-02: If your Perl installation is recent and not found in the OS location at /usr you will need this patch to build the Perl CA library. This is not needed on Windows where the Perl CA library is not currently supported for compiler compatibility reasons.
• 64-bit Windows builds of the CAS library may not work with some compilers. The code in src/legacy/gdd is currently incompatible with the LLP64 model that Windows uses for its 64-bit ABI.
