Defining _XOPEN_SOURCE explicitly in the source file leads to all kinds
of cross-platform headaches, plus incompatibilities between
configure-time capabilities and compile-time features. Let autoconf sort
out how to expose the largest number of functions in a way that is
consistent between configuration and compilation.
Previously we needed the cflags to include the original HAVE_ICONV value
so that MdbHandle looked the same to client applications as it did to
the compiled library. Now we use a .in file for the header so that these
definitions are not necessary when the client is compiling.
Add new mdbi_register_backend2 function with the features introduced in
PRs #321 and #322. The purpose is to prevent API/ABI breakage in the
1.0 release.
Access's `LIKE` is actually case-insensitive, but to prevent breaking existing
programs that rely on mdbtools' case-sensitive behavior, introduce a new
`ILIKE` operator to perform a case-insensitive match. Use GLib's `g_utf8_casefold`
to make the comparison UTF-8 aware. A "poor man's" version is implemented
in fakeglib, which relies on `towlower`, and won't work with multi-grapheme
case transformations (e.g. German Eszett).
Fixes#233
Use a local variable instead of casting the address of a SQLSMALLINT
to a (size_t *). sizeof(SQLSMALLINT) < sizeof(size_t) so gcc is
rightfully giving the following errors when building on Fedora 34:
