System APIs in CE take wide char, not char. Casting doesn't convert char to
wide-char, just fools the compiler.

Use TCHAR, TEXT(), etc.

For your specific problem, either LoadLibrary(TEXT("mydll.dll")) or
LoadLibrary(L"mydll.dll").

Actually, my personal philosophy (and what I practice) is to forget about
TCHAR - always use WCHAR, L"", L''. This if you're Windows
NT/XP/CE-centric. Mitigates usage of #ifdef UNICODE/#ifdef MBCS and using
WideCharToMultiByte and MultiByteToWideChar (and associated bugs that arise
when you compile it the "other" way - "other" being MBCS defined when
normally UNICODE is defined).
