PROBLEM: 2.4.21-pre6 - "mbool" causes xconfig failure

["B. Douglas Hilton" <bdhilton@charter.net>]

[1.] One line summary of the problem:

"make xconfig fails" drivers/net/Config.in: 188: unknown command

[2.] Full description of the problem/report:

Lines 188 and 189 of drivers/net/Config.in reference a define_mbool and dep_mbool
which causes xconfig to fail. Switching these to define_bool and dep_bool allows
it to work.

[3.] Keywords (i.e., modules, networking, kernel):

mbool Config.in CONFIG_EEPRO100_PIO

[4.] Kernel version (from /proc/version):

2.4.21-pre6

[5.] Output of Oops.. message (if applicable) with symbolic information
      resolved (see Documentation/oops-tracing.txt)

Just change "mbool" to "bool", not sure what the deal is here
or what an mbool is exactly.
