Dear all, while working on a PR related to kind=4 character issues, I saw the following in gfortran.h:
/* We need to store source lines as sequences of multibyte source characters. We define here a type wide enough to hold any multibyte source character, just like libcpp does. A 32-bit type is enough. */ #if HOST_BITS_PER_INT >= 32 typedef unsigned int gfc_char_t; #elif HOST_BITS_PER_LONG >= 32 typedef unsigned long gfc_char_t; #elif defined(HAVE_LONG_LONG) && (HOST_BITS_PER_LONGLONG >= 32) typedef unsigned long long gfc_char_t; #else # error "Cannot find an integer type with at least 32 bits" #endif This seems to have been introduced by FX, but I do not really understand it. Can't we use a fixed and platform-independent type that can hold wide chars? Isn't a 32-bit / 4-byte type sufficient? Thanks for any enlightenment, Harald
