Either compile 32-bit code or use GCC to compile 64-bit fetchmail.
Note that fetchmail doesn't take advantage of 64-bit code anyways,
so compiling 32-bit SPARC code should be fine.
+* The code still isn't 100% ISO-C compliant, some configurations attempt to
+ compile files that are empty after preprocessing, which can cause compiler
+ diagnostics and perhaps jam the compilation on strict compilers.
# BUG FIXES:
* configure: detect res_* functions properly with newer glibc ABIs.
