Just a little test (construct very simple DLL and test these) with CB and these two compilers C.

What' wrong (same identical sources for the four construct) ?
Thank's.
Thierry DECHAIZE (very "old" newbie developper).
PS : All is OK with BORLAND C++, VISUAL STUDIO 2022 + kits M$, Mingw32/64, CYGWIN 32/64, MSYS264.

My questions :
Why PEDUMP /EXP give differents results beetween 32 and 64 bits ?
What are these singularies exports on 32 bits lcc ($tEssai_, $hEssai_) not present on 64 bits lcc ?
I like resolved these problems ! Help me ?
Thank's for all.
