Hello,

for the libbsd we have the problem that we expose a lot of symbols from the FreeBSD kernel space to the applications. There are several known conflicts, e.g. FreeBSD log() vs. standard math library log(). The current approach to solve this issue is to generate a file with lots of

#define xx _bsd_xx
...

defines to rename at C pre-processor level. This is however quite brittle and doesn't work in general. An alternative would be to post-process the kernel-space object files with something like this

objcopy --redefine-syms redefines.txt x.o

with a redefines.txt

xx=_bsd_xx
...

My question is now: how can I add this post-processing step to the waf based libbsd build system?
