Re: Bug in AX_APPEND_LINK_FLAGS

[Peter Simons]

Hi Mike,

you submitted the following patch to AX_APPEND_LINK_FLAGS a while ago:

  
http://git.savannah.gnu.org/cgit/autoconf-archive.git/commit/m4/ax_append_link_flags.m4?id=7d5e9315f7b93843f7d65699eebfec742323a483

Now, Peter De Wachter reports the following phenomenon:

Do you, by any chance, have an idea how to explain and/or remedy this
behavior?

Take care,
Peter
