Extension building problems

I am having problem building extension with long names. As an example say my extension name is foooo_naaaaame_baaaaar and FOOOO_NAAAAAME_BAAAAAR_SHARED_LIBADD is used to link libraries. The problem is when the Makefile is generated I get FOOOO_NAAAAAME_BAAAAAR_SHARED_LIBADD at the top of the Makefile, but FOOOONAAAAAMEBAAAAAR_SHARED_LIBADD at the bottom for the link line. If I change line 1224 of acinclude.m4 from: $3/$1.la: \$($2) \$(translit($1,a-z-,A-Z_)_SHARED_DEPENDENCIES) to: $3/$1.la: \$($2) \$(translit($1,a-z_-,A-Z__)_SHARED_DEPENDENCIES) it works fine. What else is strange is that if I shorten the name it works with out the change (foooo_baaaaar works). Did something change recently to cause this? If nobody sees a problem with the change I am going to check it in. Thanks, Brian
