- Subject: Warning "_XOPEN_SOURCE" redefined while building libf2c/libI77/open.c
This was on a Debian Woody (test release) sun4m system using
binutils 2.12.90.0.1-1
dejagnu 1.4.2-1.1
gcc 2.95.4-9 (Debian prerelease)
kernel-image-2.2.20-sun4dm-smp 9
libc6 2.2.5-3
While bootstrapping gcc-3.1 I've been getting this warning:
/share2/gcc-rel/gcc/objdir/gcc/xgcc -B/share2/gcc-rel/gcc/objdir/gcc/ -B/usr/local/sparc-linux/bin/ -B/usr/local/sparc-linux/lib/ -isystem /usr/local/sparc-linux/include -c -DSkip_f2c_Undefs -DAllow_TYQUAD -I. -I../../../../libf2c/libI77 -I.. -I../../../../libf2c/libI77/.. -DHAVE_CONFIG_H -g -O2 ../../../../libf2c/libI77/open.c -fPIC -DPIC -o .libs/open.o
In file included from ../../../../libf2c/libI77/open.c:4:
config.h:35:1: warning: "_XOPEN_SOURCE" redefined
../../../../libf2c/libI77/open.c:3:1: warning: this is the location of the previous definition
Is this something to be preoccupied with?
Cheers,
