when emerging m4 on a uclibc based host tests fails on test : "test-fseeko.sh" test-fseeko fails on the last test in test-fseeko.c: fseeko (stdin, (off_t) 0, SEEK_END) feof (stdin) <- EOF is found (return value = 4 ) according to feof man page : The function feof() tests the end-of-file indicator for the stream pointed to by stream, returning nonzero if it is set. and fseek man page : A successful call to the fseek() function clears the end-of-file indicator for the stream so feof should return 0 as expected by this test ? looks like the problem comes from the uclibc implementation of fseeko ?

There's a new snapshot of m4 that will probably became m4-1.4.12, you could try to see if the bug got fixed in it or report upstream before the new stable release: Eric Blake wrote: I have released a new snapshot from branch-1.4, and hope to release it as M4 1.4.12 in the near future. This should fix many of the complaints about strtod and other test failures that were reported against 1.4.11. However, it also introduces a new optional dependency on libsigsegv [1]. It also swaps the order of the two testsuites, so that the m4 tests are run prior to the gnulib tests. Therefore I would appreciate some feedback before making the 1.4.12 release (if you encounter a testsuite failure in the m4 suite, please rerun with 'make -k check' before reporting it, so that the gnulib testsuite is also run).

Created attachment 162678 [details] log-m4.txt thanks for the comment, but it still fails, I'll see if i have time for reporting it upstream ...
Still an issue with 1.4.15 or .16?
