[Help-glpk] autoreconf issue and octave

[Marco Atzeri]

Dear developers,
building the glpk package for cygwin I always had problem
with autoreconf as autoheader complains of missing template for

HAVE_GMP, HAVE_ZLIB, HAVE_LTDL, HAVE_DLFCN, ODBC_DLNAME], 
MYSQL_DLNAME.

The attached patch solve the issue and also allow me
the building in a separate directory from src directory.


The last portion is probably eccessive
**************************************************
 
 lib_LTLIBRARIES = libglpk.la
 
-libglpk_la_LDFLAGS = -version-info 21:0:21 \
--export-symbols-regex '^(glp_|_glp_lpx_).*'
+libglpk_la_LDFLAGS = -version-info 21:0:21
 
 libglpk_la_SOURCES = \
 glpapi01.c
**************************************************

but the regex is cutting two functions 
currently used by octave (www.octave.org)

void _glp_lib_print_hook (int (*func)(void *info, char *buf), void *info);
void _glp_lib_fault_hook (int (*func)(void *info, char *buf), void *info);

is it possible to have these two functions exported 
as in the past ?


Thanks
