Fallout 2 utility Vanilla scripts included with the BIS Mapper won't compile

I was trying to compile sierra\wsklaxon.ssl and noticed that it wouldnt compile and kept complaining that it was expecting a top level statement in condition.h.

Even the vanilla version of the file will not compile. I even reinstalled all the scripts from the BIS mapper program in this order : vanilla -> 1.02 patched scripts -> killap's scripts. It still will not compile, and this is with a unedited script folder.



Again, i have done a full reinstall of the script folder...and it still will not compile this vanilla script. I have not touched the header folder at all after the reinstall.

Any ideas as to what is going on?

Edit : Nevermind, same issue as here : https://www.nma-fallout.com/threads/hook-script-help-rp-2-3-3-source-headers-fail-to-compile.203382/
