Actually, yes, I was using a slightly modified make.conf. After playing
around for a while it turned out that the "problem" was a CONFIGARGS?=-g
line, which changed the gcc invocation to -O instead of the default -O2.
Again, after playing around with the gcc options a bit, it turns out
that -O2 includes -funit-at-a-time, making gcc parse the whole cxgb_sge.c
before the compilation, so that it can see the refill_rspq() function
body and it can inline it properly.
So... I'm not sure what the proper solution ought to be - either figure
out a way to add -funit-at-a-time to CFLAGS (which might not work all
that well with non-gcc compilers, I guess), or move the function body up
as per my original suggestion.

I had to translate this sentence into English because I could not read the original Sanskrit.
