Update.
1999-05-27 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * malloc/malloc.h: Properly handle future GCC versions. 1999-05-27 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * sysdeps/unix/sysv/linux/configure.in: Change version checks to use AC_EGREP_CPP. Change sed pattern to not use alternation. Fix text of error message. * aclocal.m4 (GLIBC_PROVIDES): Define AC_LANG to `C'.
