Launch4j Executable Wrapper

I'm trying to build a version for Solaris x86. When I try to use the build I get this error: [launch4j] /export/home/rodgerb/projects/launch4j/launch4j/w32api/crt2.o: file not recognized: File format is ambiguous [launch4j] /export/home/rodgerb/projects/launch4j/launch4j/w32api/crt2.o: matching formats: coff-i386 pe-i386 I've compiled the GNU MiniGW with the options (--enable-targets=i386-pc-solaris2.10,i386-pc-mingw32) and see pei-i386 in the list of supported targets for ld. I've double checked the file crt2.o file matches a working version of Launch4j (on my WindowsPC). Sum shows 43973 5 crt2.o Any suggestions?
