Hello, I started getting new compile warnings during compilation of
mingw-w64 runtime.
In file included from math/modfl.c:6:
.../mingw-w64-headers/crt/fenv.h:64:39: warning: ‘__mingw_fe_dfl_env’
initialized and declared ‘extern’
extern const __MINGW_SELECTANY fenv_t __mingw_fe_dfl_env = { 0, 0 };
^~~~~~~~~~~~~~~~~~
.../mingw-w64-headers/crt/fenv.h:72:39: warning: ‘__mingw_fe_pc64_env’
initialized and declared ‘extern’
extern const __MINGW_SELECTANY fenv_t __mingw_fe_pc64_env = { 0x3f3f003f, 0 };
^~~~~~~~~~~~~~~~~~~
.../mingw-w64-headers/crt/fenv.h:76:39: warning: ‘__mingw_fe_pc53_env’
initialized and declared ‘extern’
extern const __MINGW_SELECTANY fenv_t __mingw_fe_pc53_env = { 0x3f3f103f, 0 };
^~~~~~~~~~~~~~~~~~~
I think that it is related to commit 9c27617e016f ("headers: Use
selectany fenv_t pointers for FE_*_ENV macros.").
For me it looks really a bad idea to define a global variable in public
header file with value and also with extern keyword.
