Annotation of OpenXM_contrib/gnuplot/configure.in, Revision 1.1.1.1
1.1 maekawa 1: dnl Process this file with autoconf to produce a configure script.
2: dnl configure.in for gnuplot 3.7 on Unix.
3: dnl
4: dnl Where possible, please adopt a convention that the absense of
5: dnl a macro is the usual case : this saves having to update
6: dnl countless makefiles when new tests are added. By usual case
7: dnl I guess ansi compiler on posix system or something like that
8: dnl
9: dnl [Lars: this is no longer necessary. I have cut this stuff out
10: dnl of configure.in and added the necessery definitions to syscfg.h.
11: dnl This reduced the size of configure by 30k!
