is available in a FILE structure, which is needed by char-ready. * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and FILE_CNT_READPTR. * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw exceptions using misc_error instead of syserror. It seems a bit odd to throw an exception if a string can't be found in the environment, but it's consistent with open-file, stat etc. (simpos.h): remove sys_ from getenv. * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error occurs, throw an error instead of returning errno. Return value is now unspecified. (numerous in posix.c and posix.h): removed superfluous sys_ from names.
