If sql.h exists, sqlext.h also must exist, because these headers are
always used together.

Under windows the configure script, which tunes config.h, has sense
only if you are using cygwin. AFAIK the cygwin core includes w32 api,
in particular, windows.h, so there is no need to check windows.h in
the configure script.

If you have a cygwin version of MySQL, you can configure and build
glpk as usual.

If you need to compile glpk with a non-gnu compiler (like msvc), you
should make necessary changes in glpsql.c by yourself. Please see:

BTW, sql.h and sqlext.h are ODBC headers; MySQL header is mysql.h.
