This means that no previous declaration was present for the function 'malloc' and/or 'realloc'. The reason is that since 2010-06-09, gnulib/lib/setenv.c has a "#undef malloc" and "#undef realloc", and unlike most other gnulib overrides, the "#define malloc rpl_malloc" is done _before_ the system's <stdlib.h> is included, not after it is included. > As I said earlier, the fix is to cast the return values from malloc() and > realloc() to (char *), which seem to satisfy the HP compiler. This "fix" would do the wrong thing on 64-bit platforms. Your immediate workaround should be to remove the two #undefs from setenv.c. I'll post a fix to bug-gnulib. Thanks for the report! Bruno
