The Gnu libc v2.2 changes the type definition of fpos_t from a long to a struct with a long int(__pos) and a structure dealing with conversions of multibyte characters(_mbstate). This causes the compilation of iomonads.c to fail with errors at lines 715 and 736 since fpos_t seems to be treated as a long. A quick fix that seems to work is to change config.h to comment out the defines for fgetpos and fseekpos. I tried making the appropriate changes in the references to variables of type fpos_t but I got a compilation error and didn't investigate further. Also the pos member of the fpos_t is a 64 bit integer so that files greater than 2GB can be manipulated. It seems that the current typecast from fpos_t to int seems to have the potential for problems with files greater than 2GB on 32bit platforms. FYI, glibc is currently only used on redhat 7 systems but other linux distributions will probably migrate to it in the future. Shop Safely Online Without a Credit Card http://www.rocketcash.com
