This fixes a problem where on Windows the prefix would
not match if the prefix is generated with backslashes
and the rest of the variables use normal slashes
If a key is defined with no value, dequote will allocate a buffer with a
length of 0. Since the buffer's length is 0, any manipulation of its
content is UB.
Example .pc file:
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

client: use BELIBRARIES
On Haiku, BELIBRARIES is the equivalent to LIBRARY_PATH on many other
systems, while LIBRARY_PATH is instead the LD_LIBRARY_PATH of Haiku.
pkg: bootstrap package search paths with Haiku's find_paths
This commit adds build_default_pkgconfig_path. The function appends
to the list given the default pkgconfig paths, and will supersede
get_default_pkgconfig_path
we now use POSIX-style quoting for all fragments. it is our belief that this is the
most optimal behaviour for portability, because all POSIX-compliant tools require
single-quotes to be considered as literal (closes#153).
because of this, we are able to remove some hacks on the lexer side which were there
to simulate pkg-config quoting, but were basically utterly wrong (closes#139).
