Now, ./configure checks for their presence. If they are absent, they will be defined automatically for you in include/sane/config.h. If they are present, these defines are not provided and whoever uses them will need to add an #include for a header that does, normally sys/types.h. However, that header may be absent itself, so ... Somehow, I get the impression that ./configure is only doing half of this job. On the other hand, (blindly?) including sys/types.h in the config.h file seems pretty heavy handed too. Moreover, that file may not be there. Now, if the issue is just u_char and friends, can't we just simply avoid the whole issue and replace them with "unsigned char" and the like? For all I know that ought to work everywhere. A similar suggestion was made (way back) on StackOverflow[1]. [1] http://stackoverflow.com/questions/1918934/is-u-char-a-standard Grepping for the ones that ./configure checks for (SANE_CHECK_U_TYPES in acinclude.m4) with: $ git grep -wE 'u_(char|short|int|long)' master | wc -l 2084 that would be quite a monster patch though. Would such a patch be acceptable? # There are false positives in the above, e.g. the ones in acinclude.m4 # and in include/sane/config.h and its template. I realize that this is not Yurii's sigset_t problem but thought I would mention it anyway.
