[Frama-c-discuss] Frama-C: #define not taken into account into annotations

#define are not taken into account in annotations.
Of course *this is not a bug*: this is due to pre-processing of C
modules, before launching analysis.
But from a final user's point of view, when annotating source code, this
may be an issue, as one has to "navigate" among .h hierarchy to find the
actual definition of terms and replace it into annotations (this can
result into a loose of time when dealing with huge auto-generated C
modules embedding an important number of #define).
A simple example to illustrate the purpose:
//===== f.h
#define vx 0.0
//===== f.c file
#include "f.h"
float main(float v) { /*@ assert v<=vx ; */ return v; }
//===== stdout of frama-c f.c
[preprocessing] running gcc -C -E -I.   e1.c
File e1.c, line 6, characters 14-16:
Error during analysis of annotation: unbound logic variable vx
e1.c:6: Warning: ignoring logic code annotation
Is there any means to make such annotations compliant with #define?
Best regards,
