* linux/bip6: Use function over PRINTF macro Our repo should be C89 compatibale. C89 does not support variac macros. For this reason use variac functions. This also enables to print different streams than just stderr. Also now if something is changed in debug_fprintf it also affect here which is good. * Use __inline__ over inline in library Use __inline__ over inline as that is C89/C90 combatible. With MSVC we need to use __inline so just define __inline__ to it if not already. * h_get_alarm_sum: Fix -Wself-assign compiler warning We get Wself-assign if PRINT_ENABLED is 0 ``` src/bacnet/basic/service/h_get_alarm_sum.c:129:16: warning: explicitly assigning value of variable of type 'int' to itself [-Wself-assign] [build] 129 | bytes_sent = bytes_sent; [build] | ~~~~~~~~~~ ^ ~~~~~~~~~~ ``` --------- Co-authored-by: Kari Argillander <kari.argillander@fidelix.com>
