It seems that the newer libc don't consider it appropriate if the return values of libc function is not used. This causes make to fail.
Thanks and regards

Please be more specific. What exact error? What compiler? What
operating system?

... and what GDB version. It sounds like he's referring to warnings
from glibc's (ab)use of warn_unused_result, which Jim Blandy
fixed months ago:

Does the --disable-werror configure option work in gdb?

GDB 6.8 was released in early 2008. I think we missed
disable -Werror in that release.

^^^^^^^
2009-01 > 2008-xx.
Either try a recent GDB snapshot, or build 6.8 with "-Wno-unused-result"
added to CFLAGS, or configure with --disable-werror.

How libc can enforce such a "consideration" on usage of return
values?

GCC has a `warn_unused_result' attribute.
