Hello, I'm having problems with wchar in Linux. I've built expat with:

./configure --prefix=/home/humpback/bin/expat CFLAGS="-g -O2
-fshort-wchar" CPPFLAGS="-DXML_LARGE_SIZE -DXML_UNICODE_WCHAR_T"
--disable-shared --enable-static
make buildlib LIBRARY=libexpatwf.la
make installlib LIBRARY=libexpatwf.la

I then modified one of the samples provided in expat and built (source is attached):


g++ -DXML_LARGE_SIZE -DXML_UNICODE_WCHAR_T -O0 -g3 -Wall -c
-fmessage-length=0 -MMD -MP -MF"expattests.d" -MT"CPPTestes.d"
-o"expattests.o" "expattests.cpp"

g++  -L/home/humpback/bin/expat/lib -o"expattests"  expattests.o -lexpatwf

When i run the resulting code I get errors in printf because the data is
not valid. Can someone help me?
