Description Aleksandr Platonov 2013-02-19 07:57:47 UTC 
Example code:
#define a someting
#undef a
int a()
{
    return 0;
}

Doxyfile:
ENABLE_PREPROCESSING   = YES
MACRO_EXPANSION        = YES
EXPAND_ONLY_PREDEF     = NO
INPUT = test.c

Result:
Macros
#define 	a   someting
Functions
int 	someting ()

But should be:
Macros
#define 	a   someting
Functions
int 	a ()


This is regression (#undef works correctly in 1.7.3)

Thanks, I'll use your patch posted on doxygen-develop:

This bug was previously marked ASSIGNED, which means it should be fixed in
doxygen version 1.8.5. Please verify if this is indeed the case. Reopen the
bug if you think it is not fixed and please include any additional information
that you think can be relevant.
