Rather than having a different patch file for each platform and refusing to
code fseek/tell because we can't do SEEK_CUR, why not check for FSEEKO64
and revert to a simple solution:
#ifdef HAVE_FSEEKO64
#define FSEEK fseeko64
#define FTELL ftello64
#define FILE_OFFSET off64_t
#else
#ifdef HAVE_FSEEKO
#define FSEEK fseeko
#define FTELL ftello
#define FILE_OFFSET off_t
#else
#if HAVE_FSEEK_BETTER_THAN_32_BIT
#define FSEEK FSEEK_BETTER_THAN_32_BIT
#define FTELL FTELL_BETTER_THAN_32_BIT
#define FILE_OFFSET FILE_OFFSET_BETTER_THAN_32_BIT
#else
#if sizeof(off_t) > sizeof(long)
#define IGNORE_FSEEK
#else
#define FSEEK fseek
#define FTELL ftell
#define FILE_OFFSET long
#end if...
Then use a correct checkSeek which also checks IGNORE_FSEEK.
AFAICT, this *will* do the job on all systems discussed. And we can
certainly skip the HAVE_FSEEK_BETTER_THAN_32_BIT bit, but coding a trivial
seek/tell pair for fsetpos/fgetpos is easy, even in a macro.
