I think you are allowed to use C99 [1] which has it -- see eg http://stackoverflow.com/questions/4159713/how-to-use-boolean-datatype-in-c Dirk [1] Section 1.6.4 opems with 1.6.4 Portable C and C++ code ----------------------------- Writing portable C and C++ code is mainly a matter of observing the standards (C99, C++98 or where declared C++11/14) and testing that extensions (such as POSIX functions) are supported.
Ah, but I'm *not* using C at all, I'm using Fortran. So I think that raising the possibility of using C99 is a communist fish[1]. I just want to make sure that my (modified) init.c is syntactically correct and robust for implementing the registration of my *Fortran* routines.
