2002-07-24 Ulrich Drepper <drepper@redhat.com> * libio/fileops.c (_IO_file_seekoff_mmap): Do use fp->_offset to compute current position. * stdio-common/tst-fseek.c (main): Improve error messages. * libio/tst-freopen.c (main): Remove unused variable. * libio/fileops.c (_IO_file_seekoff_mmap): Set fp->_offset after succesful seek call. Simply error checking. 2002-07-25 Jakub Jelinek <jakub@redhat.com> * config.h.in: Use __ASSEMBLER__ test macro not ASSEMBLER. * sysdeps/ia64/fpu/libm_support.h: Likewise.

// History: 02/02/2000 Initial version

// 3/22/2000 Changes to support _LIB_VERSION variable

|
|
// 5/31/2000 added prototypes for __libm_frexp_4l/8l
|
|
// 8/10/2000 Changed declaration of _LIB_VERSION to work for library
|
|
// builds and other application builds (precompiler directives).
|
|
// 8/11/2000 Added pointers-to-matherr-functions declarations to allow
|
|
// for user-defined matherr functions in the dll build.
|
|
// 12/07/2000 Added scalbn error_types values.
