Hi Paolo, The mathl module, compiled on Cygwin with -Wall, yields several warnings:
1) acosl.c:186: warning: implicit declaration of function `asinl' acosl.c:186: warning: implicit declaration of function `sqrtl' asinl.c:186: warning: implicit declaration of function `sqrtl' Calling functions with 'long double' results when they are not declared most often yields wrong results, so this is probably not harmless. 2) trigl.c:217: warning: suggest explicit braces to avoid ambiguous `else' Look at trigl.c lines 215-216. The condition on x can never be true. What is the purpose of this code? 3) tanl.c:128: warning: 'flag' might be used uninitialized in this function The 'flag' is indeed used uninitialized. 4) logl.c:193: warning: unused variable `u' logl.c:194: warning: unused variable `m' These look harmless. But why not remove the two unused variables? Bruno
