Problem solved by updating the gcc I use to build the current subversion version to 4.2.0.

Ok, next Problem:
$GCC_BUILD_DIR/i686-pc-mingw32/libstdc++-v3/include/limits:1011: error: '__FLT_HAS_DENORM__' was not declared in this scope $GCC_BUILD_DIR/i686-pc-mingw32/libstdc++-v3/include/limits:1068: error: '__DBL_HAS_DENORM__' was not declared in this scope $GCC_BUILD_DIR/i686-pc-mingw32/libstdc++-v3/include/limits:1125: error: '__LDBL_HAS_DENORM__' was not declared in this scope

Here I'm stuck because I'm unable to find the defining header or source file for these constants... Any ideas?

The values of these definitions are computed by the compiler in gcc/c-cppbuiltins.c
(c_cpp_builtins).

Can you provide preprocessed source without macro expansion? I'm curious
why a Windows hosted toolchain doesn't call c_cpp_builtins.

Cheers,
Carlos.
