In other environments 226ca2c52aSchristosdnl we can use the inet-types in <sys/types.h> which would define the 236ca2c52aSchristosdnl typedefs int8_t and u_int8_t respectivly. 246ca2c52aSchristosdnl 256ca2c52aSchristosdnl This macros will create a local "_stdint.h" or the headerfile given as 266ca2c52aSchristosdnl an argument. In many cases that file will pick the definition from a 276ca2c52aSchristosdnl "#include <stdint.h>" or "#include <inttypes.h>" statement, while 286ca2c52aSchristosdnl in other environments it will provide the set of basic 'stdint's defined: 296ca2c52aSchristosdnl int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t 306ca2c52aSchristosdnl int_least32_t.. int_fast32_t.. intmax_t 316ca2c52aSchristosdnl which may or may not rely on the definitions of other files. 326ca2c52aSchristosdnl 336ca2c52aSchristosdnl Sometimes the stdint.h or inttypes.h headers conflict with sys/types.h, 346ca2c52aSchristosdnl so we test the headers together with sys/types.h and always include it 356ca2c52aSchristosdnl into the generated header (to match the tests with the generated file). 366ca2c52aSchristosdnl Hopefully this is not a big annoyance. 376ca2c52aSchristosdnl 386ca2c52aSchristosdnl If your installed header files require the stdint-types you will want to 396ca2c52aSchristosdnl create an installable file mylib-int.h that all your other installable 406ca2c52aSchristosdnl header may include. So, for a library package named "mylib", just use 416ca2c52aSchristosdnl GCC_HEADER_STDINT(mylib-int.h) 42*b2396a7bSchristosdnl in configure.ac and install that header file in Makefile.am along with 436ca2c52aSchristosdnl the other headers (mylib.h). The mylib-specific headers can simply 446ca2c52aSchristosdnl use "#include <mylib-int.h>" to obtain the stdint-types. 456ca2c52aSchristosdnl 466ca2c52aSchristosdnl Remember, if the system already had a valid <stdint.h>, the generated 476ca2c52aSchristosdnl file will include it directly.
