Hi Viktor,
As per Andi's and your suggestion, I've included <stdint.h> #if
__BORLANDC_ > 1410,
Can you check the exact version from which BCC has stdint.h to
use >= instead of > ? 1410 is 5.82 so such limit will work for
BCC 5.83 and newer. Is it intentional?
Nope, just retype mistake.
BC++ 5.5.1 aka. "BCC55" stdint.h missing. __BORLANDC__ == 1361
BC++ 5.82 aka. "BCC58" stdint.h present. __BORLANDC__ == 1410
I have no other versions of 32bit BCC.
then the redefinition warnings indeed go, but these new ones appear:
Warning W8041 source\compiler\hbmain.c 3410: Negating unsigned value
in function hb_compGenPushLong
Warning W8041 source\compiler\hbmain.c 3427: Negating unsigned value
in function hb_compGenPushLong
It effects HB_LIM_INT32 macro. It uses INT32_MIN and INT32_MAX
defines and one of them is probably wrong defined in stdint.h.
Can you check their definitions in you stdint.h? It's also possible
that the warning is side effect of internal compiler casting just
like in MAKEWORD(). I can pacify it but it may hide some real problems
in the future so before I'll touch anything I'd like to know the exact
reasons so if possible I want to see INT32_MIN and INT32_MAX
definitions
in your stdint.h and maybe some other later.
Is this BCC version freely available so I can download it and check.
Yes, it is, just a tad complicated to find it:

To save you some rounds, here's stdint.h:
