Modified files:
sys/sys cdefs.h
Log:
If using GNUC and ELF, make __IDSTRING() expand into an inline asm
statement to put the rcsid into the .comment section. This allows
the comments (ie:version id's of compiler, headers, source, etc) to be
stripped out with the standard tools (strip/objcopy). SVR4 has a
tool called 'mcs' (manipulate comment section) which allows you to
add/remove/compact strings. Removing duplicate strings helps a lot
if the headers generate them.
Using __attribute__((section(".comment"))) would probably also work,
but that still leaves the RCSID occupying C name space somewhere.
