It appears that uClibc 0.9.33.2 has fminf defined in math.h but it is not present in libm. ffmpeg configure tries to define it and gets the conflict with math.h. Since this function is not currently used in ffmpeg, I have patched out the (re-)definition for now.

Temp build fix: ca7ddc5

ok for me, thanks @thess

Looks like a bug in uClibc.

Doesn't occur with eglibc for me.

@antonlacon, please always test with uclibc, as this is the default libc
