[fpc-devel] Build failure on win64

[Sergei Gorelkin]

Hello,

I've just encountered 'make clean all OPT=-dTEST_WIN64_SEH' in trunk failure:

make ./msg2inc.exe
make[5]: Entering directory `C:/trunk/compiler'
C:/trunk/compiler/ppc3.exe -Ur -Xs -O2 -n -Fux86_64 -Fusystems -FuC:/trunk/rtl/units/x86_64-win64 
-Fix86_64 -FE. -FUx86_64/units/x86_64-win64 -dRELEASE -dTEST_WIN64_SEH -dx86_64 -dGDB -dBROWSERLOG

msg2inc.pp(823,1) Error: Undefined symbol: SYSUTILS$_$TMULTIREADEXCLUSIVEWRITESYNCHRONIZER_$__$$_DESTROY
msg2inc.pp(823,1) Fatal: There were 1 errors compiling module, stopping

While I'm not entirely sure whether this is caused by my local changes, the failed command looks 
suspicious at least.
Isn't it plain wrong to use WPO information from compiler to optimize msg2inc, a completely 
independent executable?

Regards,
Sergei
