I can confirm this on latest trunk. Its blocking bootstrap. From config log on objdir/gcc: config.log:conftest.c:2: error: parse error before "me" config.log:conftest.c:62: error: `__int64' undeclared (first use in this function) config.log:conftest.c:62: error: (Each undeclared identifier is reported only once
Note that the newly built bootstrap compiler fails the configure tests which have a trailing -V on the command line. Nearly all the various configure scripts provoke this failure. The one cited here happens to be the first.
The failure can be worked around by commenting out the section of <stdio.h> in the cygwin distribution which sets __SCLE (conversion of \r\n to \n, according to comments). The code thus commented out apparently requires some cygwin extensions in the library which have disappeared since 20070224 (quoted by submitter as last working build). I concur, having built successfully the 20070223.
(In reply to comment #2) > Note that the newly built bootstrap compiler fails the configure tests which > have a trailing -V on the command line. This is harmless, it's only for informational purpose (various tries to make the compiler display its version number, but nothing depends on this).
I have just checked in a fix for this in newlib. See the thread at: http://sourceware.org/ml/newlib/2007/msg00292.html and the references therein: http://cygwin.com/ml/cygwin/2007-03/msg00705.html http://gcc.gnu.org/ml/gcc/2007-03/msg00948.html http://gcc.gnu.org/ml/gcc/2007-03/msg01088.html This bug could be closed fixed now. cheers, DaveK
*** Bug 32134 has been marked as a duplicate of this bug. ***
This was a newlib bug which was fixed already so closing as such. You need to update your cygwin libc.
I did just run Cygwin's setup.exe and tried a few sites - even kernel.org . You can't get an update that way. It will either be by SVN/CVS or apply the patches listed in the links above to your /cygwin directory.
Created an attachment (id=13629) [edit] Fix Cygwin __sgetc_r bug with GCC 4.3.0 The information above is for patching the _source_ tree. If you obtained Cygwin gcc 3.4.4 by using the setup.exe program, the included /usr/include/stdio.h can not be used to bootstrap GCC 4.3.0. This patch is for Cygwin's /usr/include/stdio.h - it is NOT for patching GCC. It is slightly different from what is suggested for patching the _source_ ONLY in that this patch does not cause offset warning messages - otherwise it is equal (plus a few comments). It was derived from the two patches listed at: http://sourceware.org/ml/newlib/2007/msg00296.html and http://sourceware.org/ml/newlib/2007/msg00326.html combined together and applied to the "setup.exe"'s version version of /usr/include/stdio.h . It has been tested on Cygwin with GCC 4.3.0 revision 125164 .
