建立emps.c文件内容如下
/* Expand compressed LP programs (in netlib format) to MPS format.
* This is similar to the Fortran program emps.f , except that it
* understands command-line arguments, including the -m option,
* which causes "mystery lines" to be included in the output.
* ("Mystery lines" allow extensions to MPS format. At the time of
* this writing, however, none of the netlib problems contain
* mystery lines.)
*
* Written by David M. Gay of AT&T Bell Laboratories.
*
* For use on MS-DOS machines, you must supply routines described in
* the comments near the #ifdef MSDOS and #ifndef MSDOS lines below.
*
* Modification to -S and -s options (31 Oct. 2000): append ".mps"
* to file names unless compiled with -DNO_dot_mps.
