CYGWIN_NT-6.1 DELTA 2.6.1(0.305/5/3) 2016-12-16 11:55 x86_64 Cygwin
>Description:
When I tried to build the tool chain using the command
./build.sh -j3 -U -m i386 -u tools
The build failed with an error message saying there were conflicting prototype declaration for the function asnprintf(), the conflict was from the file "/usr/include/stdio.h" the file from Cygwin
The full error message is as follows.
--- basename.lo ---

*** [basename.lo] Error code 1
In order to make sure it was not some cached files I re-ran the build without the -u switch, but this did not help either.
The toolchain build was working without issues until recently when
after I had updated my Cygwin installation, but I am not sure if this is what is causing the build breakage.
>How-To-Repeat:
1. Install a Cygwin in Windows 7
2. Pull the NetBSD current repository via CVS
3. Run ./build.sh -j3 -U -m i386 -u tools
>Fix:
As a temporary solution I edited the file "/usr/include/stdio.h" commented the lines 288 and 289.
char * _EXFUN(asnprintf, (char *__restrict, size_t *__restrict, const char *__restrict, ...)
_ATTRIBUTE ((__format__ (__printf__, 3, 4))));
After this I re-ran ./build.sh -j3 -U -m i386 -u tools which then build the toolchain without issues.
