Hopefully I'll have time this evening to sort out a patch to post.
I found that dev86-0.16.3 has a number of build issues, so I had to
modify some of the makefiles, etc. as well.
Anyway, here's a list of my bcc tweaks (as best I recall):
1) #elif support.
2) #warning support (at least for non-continued lines).
3) Support asm() at file scope. This is to allow the equivalent
of #asm/#endasm in macros.
4) Limited support for things like "#define stdio stdio". Stock bcc
goes into an infinite loop when encounting this. The implementation
has flaws, but it does what I needed. You see this a lot in the
glibc headers we're using with uClibc (yes I'm working on a port).
5) Improved condition wrapping of the floating point related code in
the bcc source (working towards building bcc for elks). As I said,
the code generator dies... at least using elksemu.
Manuel
