[Confuse-devel] [PATCH 1/4] confuse: ISO C90 does not support the ‘%lf’ printf format

[Carlo Marcelo Arenas Belon]

'%f' is valid for float and double, while '%Lf' is needed for long double
leaving this as a undefined behaviour for C90 and ignored in C99 as shown
by :

  confuse.c:1410: warning: ISO C90 does not support the ‘%lf’ printf format
