Description:             I ran across a problem when cross-compiling for i686 on an x86 host.  While compiling GCC 3.4.5, an error occured to the toolchain, the file ctype_noninline.h was checking for glibc version with (__GLIBC__ > 2 ||  __GLIBC_MINOR__ > 2) to support two different versions of tupper/tolower typecasts.  The error occurs when the typecast supported is in fact the one that GCC claims glibc >= 2.3 supports.  At first glance, I was just going to modify that line, but looking further, I saw similar declarations all over the place.  Using a grep to /usr/include, I found that a number of the newer functions that are available, are being disabled by the __GLIBC_MINOR__ checks.  But this poses other risks of enabling support for data in which uClibc only supports the older function.
