#Mini-Crt Introduction:

This Mini-CRT (C runtime library) is a modified version of the code in the book <程序员的自我修养>.

当前支持64位的系统，在linux和windows下测试通过。

Environment:

Linux or Windows

In Linux x86:

gcc -c -fno-builtin -nostdlib -fno-stack-protector entry.c malloc.c stdio.c string.c atexit.c

g++ -c -nostdinc++ -fno-rtti -fno-exceptions -fno-builtin -nostdlib -fno-stack-protector crtbegin.cpp crtend.cpp ctors.cpp new_delete.cpp sysdep.cpp iostream.cpp sysdep.cpp

ar -rs minicrt.a malloc.o stdio.o string.o ctors.o atexit.o iostream.o new_delete.o sysdep.o

g++ -c -nostdinc++ -fno-rtti -fno-exceptions -fno-builtin -nostdlib -fno-stack-protector test.cpp

ld -static -e mini_crt_entry entry.o crtbegin.o test.o minicrt.a crtend.o -o test

In Linux x64:

gcc -c -fno-builtin -nostdlib -fno-stack-protector entry.c malloc.c stdio.c string.c atexit.c -DX64

g++ -c -nostdinc++ -fno-rtti -fno-exceptions -fno-builtin -nostdlib -fno-stack-protector crtbegin.cpp crtend.cpp ctors.cpp new_delete.cpp sysdep.cpp iostream.cpp sysdep.cpp -DX64

ar -rs minicrt.a malloc.o stdio.o string.o ctors.o atexit.o iostream.o new_delete.o sysdep.o

g++ -c -nostdinc++ -fno-rtti -fno-exceptions -fno-builtin -nostdlib -fno-stack-protector test.cpp

ld -static -e mini_crt_entry entry.o crtbegin.o test.o minicrt.a crtend.o -o test

In Windows:
