Euphoria Ticket #965: tdm gcc 5.1 source/be_machine.c:2542: undefined reference to `roundup'

tdm gcc 5.1.0 from

when linking eui.exe for 64 bit on windows 
/intobj/back/be_machine.o: In function `C allBack': 
/source/be_machine.c:2542: undefined reference to `roundup' 
/intobj/back/be_socket.o: In function `eu sock_getservbyport': 
/source/be_socket.c:1345: undefined reference to `NOT_USHORT_V ALUE' 
/intobj/back/be_socket.o: In function `eu sock_close': 
/source/be_socket.c:1573: undefined reference to `IS_SOCKET' 
more undefined references to `IS_SOCKET' follow 
gcc makefile for windows seems to be broken for many months.

I wasn't able to build 4.1 or 4.0 with simple make for many previous revisions. though I am able to make library interpreter ok with tdm gcc 4.9

eui -v works and I can run bin/bugreport.ex but most of the other demos silent exit. same with --debug

I am not able to build debug with no managed memory

build of previous revisions with tdm gcc 4.9 for 32 bits work ok

Maybe tdm gcc 5.1 is broken with respect to use of the 'inline' keyword? Try removing the 'inline' keyword from their definitions ( at and and ) and then doing a distclean and a build.

same link error with MinGW64 gcc 6.3 from

I will look at the inline references. maybe they changed the header names?

why are we even static linking to sockets? shouldn't that be easy enough to lazy link at runtime? I never use them

Thanks to Shawn Pringle, we are doing a dynamic, run-time 'link' with function pointers.

See and and

The inline functions causing problems aren't external references but internal ones that do stuff like tell us if an Euphoria object represents a socket or not - stuff that can't be outsourced to an external third-party or OS library.
