size_t problem in include files

size_t problem in include files

[Tahir Abdullah]

Hi folks
I am trying to compile my program on GCC 3.3.1 but in many header files like 
unistd.h, string.h and some other headers, i find the following errors:
error: type specifier omitted for parameter 'size_t'
error:'size_t' is used as a type, but is not defined as a type.

What is the problem. Thanks in advance

Hi Tahir,

Put this line near the top of your header file section in your C source code:
#include <stddef.h>

Note, I am surprised that the C header files unistd.h and string.h are not 
including stddef.h already.

HTH,

string.h is required to declare size_t (C99, 7.21.1/1).  Bug?
