ld: main.o: relocation R_X86_64_PC32 against undefined hidden symbol `IID_IClassFactory' can not be used when making a shared object

When compiling wineasio on gentoo amd64, I get the following error:

gcc -c -I. -I/usr/include -I/usr/include -I/usr/include/wine -I/usr/include/wine/windows    -g -O2 -D__WINESRC__ -DNATIVE_INT64 -D_REENTRANT -fPIC -Wall -pipe -fno-strict-aliasing -Wdeclaration-after-statement -Wwrite-strings -Wpointer-arith -o regsvr.o regsvr.c

I find a wineasio fork on github which compile fine: https://github.com/Jajcus/wineasio

That fork compile only with the 64 bits version.

I get the 32 bits version to compile by adding "-L/usr/lib32/${WINE_FLAVOR_INSTALLED}/wine -L/usr/lib32/${WINE_FLAVOR_INSTALLED}" after -mnocygwin in the linker flags in Makefile.

Currently with the 64 bits distribution,s you cannot rely on /usr/lib, and with the different wine flavors, you cannot rely on /usr/lib[32|64]/wine either.
