Which one, and how did he run it?  Borland has made about a dozen
versions of C/C++ compilers in their time, supporting various target
platforms

Sorry, but I'll have to ask you leave the decision whether those
changes were minor or major to me.  IOW: I want to see that modified
source.  So please post the actual source here, and the BCC version
and command line used to build it.

Unlikely to the point of not being worth consideration.  That program is
way too simple for GCC to have a chance at miscompiling it.

No, this really must be a platform difference issue.

For the record: I did this on a laptop running XP home SP2, using
DJGPP.  And with this minor modification, OpenWatcom produces beeps,
too:

#ifdef __DJGPP__
#include <pc.h>
#endif
#include <dos.h>

int main() {
    sound(1000);
    delay(1000);
    nosound();
    return 0;
}

wcl -l=dos -bt=dos beep.c
wcl386 -l=dos4g -bt=dos beep.c
