If this is a native build, then GLIBCXX_CHECK_MATH_SUPPORT should have defined
_GLIBCXX_HAVE_FABSL
_GLIBCXX_HAVE_MODFL
in c++config.h. One would have seen something like:
checking for fabsl declaration... yes
checking for fabsl... (cached) yes
checking for modfl declaration... yes
checking for modfl... (cached) yes
when configuring. Please let me know what your see and what macros are defined
in c++config.h.
However, if this is a cross compile, then crossconfig.m4 is wrong:
*-mingw32*)
AC_DEFINE(HAVE_STRTOF)
AC_DEFINE(HAVE_STRTOLD)
GLIBCXX_CHECK_LINKER_FEATURES
;;
would have to be something like:
*-mingw32*)
AC_DEFINE(HAVE_STRTOF)
AC_DEFINE(HAVE_STRTOLD)
AC_DEFINE(HAVE_MODFL)
AC_DEFINE(HAVE_FABSL)
GLIBCXX_CHECK_LINKER_FEATURES
;;
