Re: signbit issues

[Vlad Zakharov]

Hello,

I found the same issue as discussed in this thread.

I tried to build "lftp" package for both ARC and ARM architectures using GCC 
6.2 and an error occurred:
---------------------------------->8------------------------------------
../lib/math.h:2577:1: error: ‘int signbit(float)’ conflicts with a previous 
declaration
_GL_MATH_CXX_REAL_FLOATING_DECL_2 (signbit)
---------------------------------->8------------------------------------
But when I am building it using GCC 4 or 5, I don't see any errors.

Lftp uses lib/math.h from gnulib. As I have mentioned the patch you attached 
earlier in the thread was already applied,
so issue must occur for some other reason.

Any ideas? 

Thanks.
