dnl Unfortunately on some 32 bit systems there is a problem with wx-widgets
dnl configuring itself for largefile support.  On these systems largefile
dnl support breaks C++ compiles by defining away many of the C standard library
dnl routines that should reside in namespace std::.  In order to get around
dnl problem first we have to check the largefile support macros.  Later we will
dnl use the macro SAH_LARGEFILE_BREAKS_CXX to check for the breakage.  If
dnl if breakage is found LARGEFILE_BREAKS_CXX is defined in config.h.  This
dnl define is checked in std_fixes.h and the appropriate functions are defined
dnl in order to solve the problem.
