Alleged syntax error in /usr/include/linux/atmppp.h.

[Charles Trois]

G4 iMac with YDL 4.0.1.

I'm having trouble in installing ppp-2.4.3:

make[2]: Entering directory
`/home/moi/travaux/ppp-2.4.3/pppd/plugins/pppoatm'
gcc -O2 -g -I../.. -I../../../include -fPIC -I. -c -o pppoatm.o pppoatm.c
In file included from pppoatm.c:25:

pppoatm.c:118: error: `atm_backend_t' undeclared (first use in this
function)
pppoatm.c:118: error: (Each undeclared identifier is reported only once

make[2]: *** [pppoatm.o] Error 1
make[2]: Leaving directory
`/home/moi/travaux/ppp-2.4.3/pppd/plugins/pppoatm'

There are two errors here, but I presume that the second error just
reflects the first one.

Here is the full text of atmppp.h:

It looks all right to me, but Splint also points out something:

[root at sirrah travaux]# splint /usr/include/linux/atmppp.h
Splint 3.1.1 --- 25 May 2004
/usr/include/linux/atmppp.h:20:15: Parse Error. (For help on parse
errors, see splint -help parseerrors.)
*** Cannot continue.

Where is the bug?
