/* Function declarations for libiberty. Written by Cygnus Support, 1994. The libiberty library provides a number of functions which are missing on some operating systems. We do not declare those here, to avoid conflicts with the system header files on operating systems that do support those functions. In this file we only declare those functions which are specific to libiberty. */ #ifndef LIBIBERTY_H #define LIBIBERTY_H #include "ansidecl.h" #ifdef NeXT #define xmalloc malloc #define xrealloc realloc #endif /* NeXT */ /* Build an argument vector from a string.
