m4_foreach causes the loop to be expanded at m4 time (a larger configure
file). In this case, you could probably easily get by with a shell loop
instead, for a smaller configure file (untested):
for type in 'char **' 'const char **'; do
AC_RUN_IFELSE([AC_LANG_PROGRAM([[
...
typedef $type gl_iconv_buf_t;
