Secondly this is not bug. Try to build the example code with -Wall: [bode:/tmp]$ gcc -Wall -o ld1 ./ld1.c ./ld1.c: In function 'main': ./ld1.c:5: warning: implicit declaration of function 'printf' ./ld1.c:5: warning: incompatible implicit declaration of built-in function 'printf' ./ld1.c:5: warning: implicit declaration of function 'strtold' ./ld1.c:5: warning: format '%Lf' expects type 'long double', but argument 2 has type 'int The problem is that strtold is not declared, so gcc expects it returns an int, but actually it returns a long double. It is not declared because it is an ISO C99 function, whereas gcc uses ISO C89 as the default standard. To switch to an ISO C99 standard, either pass the -std=gnu99 flag to gcc, or define _ISOC99_SOURCE or _GNU_SOURCE, or define _XOPEN_SOURCE to a value greater or egal to 600. As this is not a bug, I am closing this bug report. Bye, Aurelien -- .''`.
