cannot build hpcgap on Gentoo x86_64 with glibc 2.26 #48

Description

@dimpase

the file it fails on is a part of glibc, so perhaps it's relevant that it is quite recent (version 2.26)

$ ./configure --enable-hpcgap
$ make
...
   WARD    src/macfloat.c => gen/macfloat.c
/usr/include/bits/mathcalls-helper-functions.h:21:29: Syntax error
extern int __fpclassifyf128 (_Float128 __value)
                            ^
ERROR: Ward failed to parse C source
make: *** [Makefile.rules:255: gen/macfloat.c] Error 1
make: *** Deleting file 'gen/macfloat.c'

(same error with ABI=32)
