The lower_bound algorithm from the stl fails to successfully compile when a proper less operator is defined to compare against the lower bound value to search for
Steps to Reproduce:
Use bcc32 -v -WC -w -x -xd -A -AT -RT to compile the attached file.

*** 2 errors in Compile ***

The code compiles successfully on both the GNU and Microsoft compilers.  It should compile with the Borland compiler as well.

Unfortunately we don't organize QC into

Borland Toolchain

While this is a problem with the toolchain, it isn't necessarily a bug in the compiler.

This code no longer produces a error when compiling for C++ Builder 10.0.2288.42451
