Re: typedef signed short int16;

[Sander Niemeijer]

I solved the problem with the help of the AC_DEFINE_INTEGER_BITS macro  
from the GNU Autoconf Macro Archive
(<http://www.gnu.org/software/ac-archive/htmldoc/ 
ac_define_integer_bits.html>) together with the following calls in my  
configure.ac:
---
AC_DEFINE_INTEGER_BITS([uint8_t], [u_int8_t], [unsigned char])
AC_DEFINE_INTEGER_BITS([int8_t], [signed char])
AC_DEFINE_INTEGER_BITS([uint16_t], [u_int16_t], [unsigned short],  
[unsigned int], [unsigned long])
AC_DEFINE_INTEGER_BITS([int16_t], [signed short], [signed int], [signed  
long])
AC_DEFINE_INTEGER_BITS([uint32_t], [u_int32_t], [unsigned short],  
[unsigned int], [unsigned long])
AC_DEFINE_INTEGER_BITS([int32_t], [signed short], [signed int], [signed  
long])
AC_DEFINE_INTEGER_BITS([uint64_t], [u_int64_t], [unsigned long long],  
[unsigned __int64], [unsigned long])
AC_DEFINE_INTEGER_BITS([int64_t], [signed long long], [signed __int64],  
[signed long])
