2.5.46 and make menuconfig weirdness

[Stephen Cameron]

Hmm, I'm seeing weird stuff with 2.5.46 and make menuconfig:

[root@zuul lx2546]# make menuconfig
make[1]: `scripts/kconfig/mconf' is up to date.
make -f scripts/Makefile.build obj=scripts lxdialog
make -f scripts/Makefile.build obj=scripts/lxdialog
./scripts/kconfig/mconf arch/i386/Kconfig
[root@zuul lx2546]# echo $?
0

Huh?  It just exits.  So, ok, run strace:

[root@zuul lx2546]# strace ./scripts/kconfig/mconf arch/i386/Kconfig

It seems to do TCGETS ioctl on every file it opens and gets ENOTTY,
although it doesn't seem that this is necessarily a problem for it.

Any ideas what's going on?
I'm running redhat's 2.4.7-10 kernel (redhat 7.1) with its tools.

It seems to read all of drivers/block/paride/Kconfig 
(8192 + 4959 bytes == whole file) then it just quits?

[...bunch of strace output deleted...]

brk(0x8089000)                          = 0x8089000
ioctl(17, TCGETS, 0xbffff350)           = -1 ENOTTY (Inappropriate ioctl for device)
