[lwip-devel] win32 port broken with LWIP_PROVIDE_ERRNO changes

[Joel Cunningham]

win32 port currently isn’t building due to LWIP_PROVIDE_ERRNO changes:

e:\projects\lwip\src\include\lwip\errno.h(46): fatal error C1017: invalid 
integer constant expression

This be because cc.h does the following:

#define LWIP_PROVIDE_ERRNO

I started on a fix, but then wasn’t sure whether LWIP_PROVIDE_ERRNO should be 
in cc.h or lwipopts.h.  The change to doc/sys_arch.txt describes 
LWIP_PROVIDE_ERRNO as still being in cc.h, but I would expect to use lwipopts.h 
to override defaults in opt.h.  Any clarification on where LWIP_PROVIDE_ERRNO 
should be defined now?

Thanks,

Joel
