The error message of GCC 4.8.1 is:
LINK git-credential-store.exe
libgit.a(mailmap.o): In function `read_mailmap':
C:\mingwGitDevEnv\git/mailmap.c:238: undefined reference to `strcasecmp'
collect2.exe: error: ld returned 1 exit status
make: *** [git-credential-store.exe] Error 1
So it's a linker error, not a compiler error.

I had to modify the example slightly to:
inline int foo(void) { return 5; }
extern int bar(int (*cb)(void)) { return cb(); }
int main(void) { return bar(foo); }
And this compiles.

This is the function definition from string.h after preprocessing:
extern __inline__ int __attribute__((__cdecl__)) __attribute__ ((__nothrow__))
strncasecmp (const char * __sz1, const char * __sz2, size_t __sizeMaxCompare)
{return _strnicmp (__sz1, __sz2, __sizeMaxCompare);}
