This is Harbour .prg code.
If harbour is run (any version, I've now tried with 1.0.1 final BCC55),
it prints: 'DEF_A AND NOT DEF_B'
If I copy the exact same code to a .c file and
try with a C compiler, there is nothing printed (with MSVC cl -W3),
which seems correct.

BTW, maybe you've missed it, but I've sent an e-mail
on strange #if behaviour. It's the same with MSVC:
---
#define DEF_A
#define DEF_B
#if defined( DEF_A ) && ! defined( DEF_B )
#error DEF_A AND NOT DEF_B
#endif
Hi,
this sound like MSVC preprocessor problem, see:
#if sizeof( MYSQL_ROW ) != sizeof( void* )
#error "MySQLDD error: sizeof( MYSQL_ROW ) != sizeof( void* )"
#endif
I GUESS your case can be "fixed" by:
#if defined( DEF_A )
#if ! defined( DEF_B )
#error DEF_A AND NOT DEF_B
#endif
#endif
Best regards,
Mindaugas
