>Release: FreeBSD 5.0-CURRENT i386
>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'
