What is there to fix in configure?  Obviously if configure looks for
alloca, and the program ignores that information, then it is a bug in
the program, not configure.

For alloca handling, see the autoconf manual.  It is more complex than
you might thing.  AIX in particular wants a certain #pragma as the
first thing in the file in order for alloca to work.
