Note that base64.c, .h are written in C, not C++. Trying to compile with g++ makes almost as little sense as trying to compile it as Fortran. The "restrict" keyword, as used, is entirely appropriate for C code, as it is part of the C language. It is not part of the C++ language (at least not yet). It's a relatively recent addition to the C language, so the restrict keyword is #defined to nothing for C compilers that don't support it (doesn't apply to modern GCC, which has supported it for a while, but _only_ when running as a C compiler). base64.c and .h expect that they are being built using a configuration-and-build environment that makes use of its autoconf macros and other dependencies that gnulib (mostly) automatically sets up for it. The m4 code that comes with these files invokes autoconf's AC_C_RESTRICT macro, which handles the case that the restrict keyword isn't supported for your compilation environment. In other words, what you're experiencing is not a bug with gnulib; it's a problem with the way you're using the code. You _really_ should be (1) using a C (not C++!) compiler, and (2) using the complete base64 gnulib module (including automake code). It's _okay_ not to do either of those two things, but note that it is not supported, and you are on your own to fix the glitches that are almost certain to come up. If you want to go ahead and continue doing it the way you're doing it, you may wish to leave the "restrict" keywords as they appear in the original source files, and pass -Drestrict= to g++, to make it easier for you to grab updated versions of those source files (though, if you do that, prepare to fix more "glitches", since, as previously mentioned, this process is not supported.) - -- HTH, Micah J.
