Packages modified in this release:

• ISOcxx v1.5
  NT distribution without rebuilds, and Sun 5.8/KAI4 support
• SpecialFunctions v1.2
  Transition to gsl 0.7 for function computation

• ZMtools v2.0

• HepTuple v2.0.1
• CLHEP v1.6.5

ISOcxx v1.5; cvs rtag V01-05-00

New Features in release:
Modification for convenient distribution in NT.
Prior to this change, after receiving a distribution of the package on NT, you would have to do a build by gmake ISOcxx.all. Now the package can be distributed in a pre-built fashion, as is prefered by D0.
Fix for KAI 4.0 on Sun 5.8.
This fix allows CDF to proceed with testing their builds on the (suddenly much more important) Sun platform. The change works but may well not be robust against moving to 5.9; it is likely that the current change will be replaced by a more polished version in the future.
New concept: EXTENSION_
At times it is necessary to detect an extension provided by a compiler, particularly if there will be some test and cure for improper behavior related to the extension. Although this often involves non-compliance, it seems wrong to call the presence of some non-standard enhancement a DEFECT.
Workaround for VC++ optimizing bug.
This was the bug that caused an internal compiler error when encountering code like

  extern "C" {double  __cdecl acos(double);}
  namespace std {using ::acos;}
  namespace std {float  acos( float x );} 

Additional defects and extensions
• DEFECT_OLD_REVERSE_ITERATOR
• EXTENSION_INCLUDE_NEXT
• EXTENSION_INCLUDE_ALIAS
• EXTENSION_LONG_LONG
• EXTENSION_LONG_LONG_STREAM_OPERATOR
Platforms checked:
• KAI 3.4 under IRIX 6.5, SunOS 5.6, Linux 6.1
• KAI 4.0b and 4.0d under Linux 6.1
• KAI 4.0d under IRIX 6.5 with and without exceptions disabled
• KAI 4.0d under SunOS 5.8 with exceptions disabled
• gcc 2.95-2 under IRIX 6.5, SUnOS 5.6, SunOS5.8, Linux 6.1
• MSVC++ V6.0 on NT4 using SRT
Dependencies:
None
Restrictions:
Possible NT dependency misses
If an ISOcxx system header changes, in principle this should trigger recompilations of any program using that header. However, if a package compiled properly under the old header, the changed header may not trigger recompilation.
This is due to the fact that VC++ cannpt be coaxed to determine dependencies, and gcc (which is therefore used for dependencies) does not respond to include_alias, which is necessary to properly allow for non-build distribution.
Note that changes in existing ISOcxx headers are and will remain rare (none has occurred yet).
We do not anticipate being able to rectify this behavior, at least until a version of VC++ that can provide dependencies is available.
Non-SRT usage mode not yet available.
Still to come:
• Documentation of the new defects and extensions is not yet in place.
• The accomodation made for KAI 4.0 on Sun 5.8 is likely to be changed for better future robustness.

  Block
  None
  HolderPtr
  None
  IteratorFilter
  Exceptions V1.2 or higher

• root v2_26_00 or higher for ROOT

CLHEP v1.6.5, cvs rtag V01-06-05

In the Matrix sub-package:
• Memory initialization for SymMatrix and GenMatrix
  When a matrix object is constructed, 25 words of memory assigned locally, for use if the matrix is relatively small. The memory used for the matrix was not being initialized; this led to some spurious floating point exceptions on Intel chips. The data used by the matrix is now zero-ed on construction, whether it is on the heap or local.
