[Openmcl-devel] Problem with files of some kind, linux x86-32

Not sure all that is required to reproduce this.

Welcome to Clozure Common Lisp Version 1.3-dev-r11045M-trunk  (LinuxX8632)!

Indeed, just (with-open-file (x "/proc/cpuinfo")) causes the same
problem.  The value is #xFFFFFFFF, so probably an error code returned
that isn't checking for a negative number correctly.

strace shows:
[pid  8335] open("/proc/cpuinfo", O_RDONLY) = 4
[pid  8335] ioctl(4, SNDCTL_TMR_TIMEBASE or TCGETS, 0xf7bbe0b8) = -1 ENOTTY (Inappropriate ioctl for device)
[pid  8335] fstat64(0x4, 0xf7bbe050)    = 0
[pid  8335] fstat64(0x4, 0xf7bbe050)    = 0
[pid  8335] ioctl(4, SNDCTL_TMR_TIMEBASE or TCGETS, 0xf7bbe0b8) = -1 ENOTTY (Inappropriate ioctl for device)
[pid  8335] fstat64(0x4, 0xf7bbe050)    = 0
[pid  8335] lseek(4, 0, SEEK_CUR)       = 0
[pid  8335] lseek(4, 0, SEEK_END)       = -1 EINVAL (Invalid argument)
[pid  8335] lseek(4, 0, SEEK_SET)       = 0
