Package: gcc-5
Version: 5.2.1-15
Severity: important

On the following C code obtained with creduce (on a code obtained
when I wanted to test MPFR 3.1.3 against GMP 4.1.4):

extern __inline__ fn1() { fn2(); }

main() {}

I get the following error with gcc-5:

$ gcc-5 -w ct.i
/tmp/ccFWIDKK.o: In function `fn1':
ct.i:(.text+0xa): undefined reference to `fn2'
collect2: error: ld returned 1 exit status

No such problem with gcc-4.9, gcc-4.8 and gcc-4.7.

not a bug. if you want to keep gnu89 inline semantics, build using -fgnu89-inline.
