Well, actually, there are a few shell functions somewhere deep
in the fat shellscript, but still it's lightyears away from
the concept of structured programming w/ functions/procedures
(introduced somewhere in the 60th).
A about 130 lines configure.ac still produces a 13.800 lines
unreadable configure script (factor 100 !).
Why isn't, eg., something like AC_CHECK_LIB just a function call ?
There could be easily one generic function that does the job on
the given parameters and also tells the success as return value,
so you could directly write:
ac_check_library 'z' 'zlibVersion' || ac_error 'zlib not installed'
instead of:
AC_CHECK_LIB(z, zlibVersion, , AC_ERROR([zlib not installed]))
(which translates to more than 60 lines of shell code in the fat script).
BTW: the whole AC_CHECK_LIB approach (trying to compile a call to
the given function name) uses broken C code - try it on GCC with
-Werror and see what happens ;-o
