Package: zlib1g
Version: 1:1.2.3.3.dfsg-12
zlib1g configure checks assume that compile fails if compiler outputs
anything, assuming it is always error message. (This is ugly, and one
may want to fix it properly.)
Compiler always gets "-fPIC", and when compiling for certain
platforms (I encountered this when compiling with MinGW32), compiler
gives warning "all code is position independent" meaning that "-fPIC"
is not needed at all. Configure checks fail because this warning
message.
Attached patch checks against that situation, and avoids using
"-fPIC" if it's not needed. For more info (and possible new versions
of the patch) see http://vcust127.louhi.net/other/crosser/
