[Help-glpk] Re: libglpk0: excessive install dependencies

[Xypron]

Hello Vijay,

thank You for testing.

In the distribution of MySQL 5.0 I installed on my computer the file 
name of libmysql.dll is not capitalized. But Windows isn't case sensitive.

I have updated my files to correct the errors:
ftp://glpk.dyndns.org/glpk/glpk-4.27-dl_r198.tar.gz

I have changed all Makefiles and batch files in w32 to compile with 
MySQL and ODBC support.
Further I  patched glpsql.c to allow compiling for MySQL with Cygwin.

Best regards

Xypron.
