autoconf/automake macro


Hello!

Nice thing to have an automake/autoconf macro with the GSL!

All problems I had with the macro disappeared from version
0.8 to 0.9, just these very pedantic remarks remain:

1. Why is the macro called "AM_PATH_GSL" and not "AC_PATH_GSL"? As far
as I understand it's more involved into autoconf than automake, isn't
it?

2. The OUTPUT-variable is called GSL_CFLAGS. The autoconf-Manual
states for the "Preset Output Variables":

" - Variable: CFLAGS
     Debugging and optimization options for the C compiler.  If it is
     not set in the environment when `configure' runs, the default
     value is set when you call `AC_PROG_CC' (or empty if you don't).
     `configure' uses this variable when compiling programs to test for
     C features.

 - Variable: CPPFLAGS
     Header file search directory (`-IDIR') and any other miscellaneous
     options for the C and C++ preprocessors and compilers.  If it is
     not set in the environment when `configure' runs, the default
     value is empty.  `configure' uses this variable when compiling or
     preprocessing programs to test for C and C++ features."

So, probably, the variable should be "GSL_CPPFLAGS"?
