Compile error for base R7.0.8.1

[Jörn Dreyer via Tech-talk <tech-talk@aps.anl.gov>]

Hello,

today I ran into a bug in EPICS base R7.0.8.1 while testing e3.

It fails to build in modules/libcom/cxxTemplates:

In file included from ../cxxTemplates/resourceLib.h:43,
                 from ../cxxTemplates/resourceLib.cpp:15:
../cxxTemplates/tsSLList.h: In member function ‘bool tsSLIterConst<T>::operator==(const tsSLIterConst<T>&) const’:
../cxxTemplates/tsSLList.h:314:32: error: ‘const class tsSLIterConst<T>’ has no member named ‘pConstEntry’ [-Wtemplate-body]
  314 |     return this->pEntry == rhs.pConstEntry;
      |                                ^~~~~~~~~~~
../cxxTemplates/tsSLList.h: In member function ‘bool tsSLIterConst<T>::operator!=(const tsSLIterConst<T>&) const’:
../cxxTemplates/tsSLList.h:320:32: error: ‘const class tsSLIterConst<T>’ has no member named ‘pConstEntry’ [-Wtemplate-body]
  320 |     return this->pEntry != rhs.pConstEntry;

Looking at the definition of tsSLIterConst one finds an pEntry member which is used at those positions in R7.0.9 but not in R7.0.8.
How to fix that?

Regards
