trouble with compiling on winxp

hi, i get this error when compiling on winxp with msvc++6
d:\11111\c plus\vc98\include\winnt.h(1092) : error C2146: syntax error : missing ';' before identifier 'KSPIN_LOCK'


this is the winnt.h where the error is at, witch seems to be ok and hasnt been modified in 4 years

Code:
