Information about the various packages used to build the current qemu
x86 binary distribution:
* gcc 2.95.2 was used for the build. A glibc 2.1.3 Debian distribution
was used to get most of the binary packages.
* wine-20020411 tarball
./configure --prefix=/usr/local/wine-i386
All exe and libs were stripped. Some compile time tools and the
includes were deleted.
* ldconfig was launched to build the library links:
