commit fb1ca2aa3e58cad474c918f34e5e5eed70f5d94a
Author: Joseph Myers <joseph@codesourcery.com>

    Support defining strtof32, wcstof32 aliases.
    
    This patch adds support for defining strtof32, wcstof32, strtof32_l
    and wcstof32_l functions as aliases of the corresponding float
    functions when _Float32 support is enabled.
    
    Tested for x86_64; also tested with build-many-glibcs.py in
    conjunction with other _Float32 changes.
    
    	* stdlib/strtof.c: Include <bits/floatn.h>
    	[__HAVE_FLOAT32 && !__HAVE_DISTINCT_FLOAT32] (strtof32): Define
    	and later undefine as macro.  Define as weak alias if
    	[!USE_WIDE_CHAR].
    	[__HAVE_FLOAT32 && !__HAVE_DISTINCT_FLOAT32] (wcstof32): Define
    	and later undefine as macro.  Define as weak alias if
    	[USE_WIDE_CHAR].
    	* stdlib/strtof_l.c: Include <bits/floatn.h>
    	[__HAVE_FLOAT32 && !__HAVE_DISTINCT_FLOAT32] (strtof32_l): Define
    	and later undefine as macro.  Define as weak alias if
    	[!USE_WIDE_CHAR].
    	[__HAVE_FLOAT32 && !__HAVE_DISTINCT_FLOAT32] (wcstof32_l): Define
    	and later undefine as macro.  Define as weak alias if
    	[USE_WIDE_CHAR].
