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].
