Configuring with CMake gives an option to configure for Visual Studio 6,
I don't find any _ATL defines in there.
Your web reference was not for this version but I was able to eliminate
the __DllMainCRTStartup@12 error by linking pcrecpp to LIBC.lib. After
that, building the test programs reported zero errors but did not create
any output exe files. Then I discovered that files with .cc extension
were not being recognized as C++ source! Once that was fixed, building
the library without linking to LIBC.lib no longer gave the unresolved
external symbol error for __DllMainCRTStartup@12. Instead it produced 75
errors (plus 2 warnings). About half are "ambiguous call to overload
function" for Arg::Arg.
I guess it would indeed be best to say the C++ wrapper is incompatible
with this version.
