I'm seeing this error on AIX 5.3. Two GNU projects effected by this are 
 * GNU patch
 * GSL (GNU Scientific library)

In the case of the former, if one configures with CFLAGS =-g0, so not to
include debugging information, the problem goes away. So when one compiles GNU
patch like this I see:

gcc -c  -DHAVE_CONFIG_H -Ded_PROGRAM=\"/usr/bin/ed\" -I. -I. -g0 quotesys.c


But the GSL Scientific library can't be compiled this way, as the users's -g0
gets in before the -g added by GSL, so one see something like:

gcc -g0 -g foo.c

which means the debugging information is still present.
