Probably the char notation as well (L'?'). For FreeBSD Char compatibility in a powerpc64 lib32 context that "long = int" should effectively instead be "int", making the conditional above = technically unnecessary. This blocks compiling lib32 source code that uses such notations as L". = . .": "long int" is not compatible with FreeBSD's Char in the powerpc64 = environment's 32 bit environment. Some compiler message are explicit = about the base types of pointers that result for the mismatches: that is = how I know that "long int" is in use for L". . ." and "int" is the other = base type involved. (Yes, freebsd64.h appears to be used for lib32, at least on powerpc64. = By contrast freebsd.h agrees for the WCHAR_TYPE_SIZE but only undef's = WCHAR_TYPE, presuming gcc defaults are correct for FreeBSD as far as the = type goes. It might need a more explicit type to be sure of a Char match = for that freebsd.h file's context.) The 4.9 vintages of powerpc64-gcc were messed up the same way, as was = noted at the time. =3D=3D=3D Mark Millard markmi at dsl-only.net
