SVN revision 4965 (personal nightly build)
Build terminates unexpectedly while compiling the CRT in mingw-w64-crt/gdtoa/strtodnrp.c, after compiling binutils, all-gcc and headers. Looks like an additional field was added to the FPI struct (int_max), which is not initialized in __strtod.
Unclear what the proper resolution ought to be -- the right thing to do looks like adding INT_MAX as the last FPI initializer.
Preprocessed source attached.
