Detailed Description

Hack for PGI and Fujitsu STLport-using compilers because of their incorrect implementation of an STL routine.

std::find_first_of(inpItr,inpItr,fwdItr,fwdItr) should use operator== for comparison. However, PGI's implementation just instantiates a std::equal_to<T> object with T=inpItrvalue_type and delegates the work to std::find_first_of(inpItr,inpItr,fwdItr,fwdItr,BinPred).

The implementation makes the wrong assumption that inpItr::value_type is the same as fwdItr::value_type and hence simply instantiates std::equal_to with one of their value_types. This breaks when inpItr and fwdItr have different value_types but the programmer has overloaded operator== to allow comparisons between compare inpItr::value_type and fwdItr::value_type.

We sidestep the issue by supplying our own binary predicate when we use std::find_first_of when charm is built with a PGI compiler.

Note:: : This hack is not needed from pgCC 10.1 onwards
