Which reminds me why I went down the supplied header path in the first place.
My tgmath.h test cases fail, for example (f is a float, d is a double):
../../../../../src/libs/math/001tgmath.c:15:7: error: assigning to 'float' from
incompatible type 'typeof (*(0
? (typeof (0 ? (double *)0 : (void *)!!((1 ? 1 : ((f))) / 2)))0 :
(typeof (0 ? (typeof ((f)) *)0 :
(void *)!!!((1 ? 1 : ((f))) / 2)))0))' (aka 'void')
f = acos(f);
^ ~~~~~~~
../../../../../src/libs/math/001tgmath.c:16:7: error: assigning to 'double'
from incompatible type 'typeof
(*(0 ? (typeof (0 ? (double *)0 : (void *)!!((1 ? 1 : ((d))) / 2)))0 :
(typeof (0 ? (typeof ((d)) *)0 :
(void *)!!!((1 ? 1 : ((d))) / 2)))0))' (aka 'void')
d = acos(d);
^ ~~~~~~~
