Dear developers, I checkout buildtools and M4 to my machine at home. I am using Fedora Core 4. The version of M4 and the buildtools are the cvs head branch. My gcc compiler is [Romulo@localhost MonetDB]$ gcc --version gcc (GCC) 4.0.2 20051125 (Red Hat 4.0.2-8) Copyright (C) 2005 Free Software Foundation, Inc.

I done boostrap, configure, and make During the compilation I got this error: /bin/sh ../../libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -I/home/Romulo/MonetDB/MonetDB4/MonetDB/src/gdk -I../.. -I/home/Romulo/MonetDB/MonetDB4/MonetDB/src/gdk -I../common -I/home/Romulo/MonetDB/MonetDB4/MonetDB/src/gdk/../common -DLIBGDK -Wall -W -std=c99 -g -Werror-implicit-function-declaration -Werror -Wno-unused-function -Wno-unused-label -D_REENTRANT -c -o libbat_la-gdk_system.lo `test -f 'gdk_system.c' || echo '/home/Romulo/MonetDB/MonetDB4/MonetDB/src/gdk/'`gdk_system.c gcc -DHAVE_CONFIG_H -I. -I/home/Romulo/MonetDB/MonetDB4/MonetDB/src/gdk -I../.. -I/home/Romulo/MonetDB/MonetDB4/MonetDB/src/gdk -I../common -I/home/Romulo/MonetDB/MonetDB4/MonetDB/src/gdk/../common -DLIBGDK -Wall -W -std=c99 -g -Werror-implicit-function-declaration -Werror -Wno-unused-function -Wno-unused-label -D_REENTRANT -c gdk_system.c -fPIC -DPIC -o .libs/libbat_la-gdk_system.o cc1: warnings being treated as errors /home/Romulo/MonetDB/MonetDB4/MonetDB/src/gdk/gdk_system.mx:224: warning: missing initializer /home/Romulo/MonetDB/MonetDB4/MonetDB/src/gdk/gdk_system.mx:224: warning: (near initialization for 'MT_system_lock.__data.__count') make[5]: *** [libbat_la-gdk_system.lo] Error 1 make[5]: Leaving directory `/home/Romulo/scratch/MonetDB/monetdb4/build/src/gdk' make[4]: *** [all] Error 2 make[4]: Leaving directory `/home/Romulo/scratch/MonetDB/monetdb4/build/src/gdk' make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory `/home/Romulo/scratch/MonetDB/monetdb4/build/src' make[2]: *** [all] Error 2 make[2]: Leaving directory `/home/Romulo/scratch/MonetDB/monetdb4/build/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/Romulo/scratch/MonetDB/monetdb4/build' make: *** [all] Error 2 [Romulo@localhost MonetDB]$ I done the same procedures several times and I always got the same error.
