[Freedos-devel] OT: Problem with C-compilers and #if

[Alain]

I hope someone here can help me with these conditionals:

        #ifdef NET_ABP
         #if NET_ABP == 1
          ...
         #else
          ...
         #endif
        #elif NET_TCP
         ...
        #endif
In fact they get a lop more intermixed than this. What happens if I write
        #if NET_ABP == 1
and NET_ABP is not defined? or even
        #if defined(NET_ABP) && NET_ABP == 1
this works in C, but would it work with compilers?
I have in mind Borland C (3.1 and 4.52) and Watcom C

thanks for any help :)
Alain
