>Organization:
none
>Environment:

5.0-current with sys/signalvar.h 1.34

>Description:

It's not possible to build a KLD without optimization if it uses the
CURSIG macro since this expand to a call to an `extern inline' function.

>How-To-Repeat:

write code that calls CURSIG
compile it without -O
kldload it

>Fix:

make the function `static __inline' instead of `extern __inline'
