Fix usage of gdlib-config
|
|
gnuplot configure.in script properly takes care of finding
|
gdlib-config using AC_PATH_PROG... but then directly uses gdlib-config
|
instead of going through the GDLIB_CONFIG variable that AC_PATH_PROG
|
has defined. Which means that whenever a gdlib-config binary not in
|
the PATH is being used, it does not use it.
