Thanks for pointing this out. I have removed the spurious declarations in CVS.

It should. But in case of problems, the same flags should be used to
compile both the PARI library and the application. In fact, Configure
determines whether included headers define a given type or declare a given
function; if a flag introduced by the application causes the compiler to
expand headers differently (e.g. due to a different set of #define's), then
Configure has been fooled and we are in trouble.

A simple workaround is to use something like

  env CFLAGS="-std=c99" Configure

Hope this helps,
