pkcs11f.h build error

This is my current build error:

...
Command line warning D4025 : overrinding '/MDd' with '/MT'
pcksmain.c
/src/include/pkcs11f.h(9) : error C2282: 'CK_EXTERN" is followed by '_CK_RV' (missing ','?)
.......
/src/include/pkcs11f.h(390) : error C2282: 'CK_EXTERN" is followed by '_CK_RV' (missing ','?)

/src/include/pkcs11f.h(390) : fatal error C1003: error count exceeds 100; stopping compilation
make: Error code 2
make: Error code 255

I just downloaded the three pkcs11 header files from the 2.01 section at www.rsa.com, and I don't understand what the problem is.
I am trying to build the 0.2 release using MKS 6.1and VC++ 5.0, on an NT 4.0 with SP4.

Any help greatly appreciated.

Thanks,
Lucien
