[Speex-dev] [PATCH speexdsp] Don't rely on HAVE_STDINT_H et al. being defined

[Tanu Kaskinen]

From: Tanu Kaskinen <tanu.kaskinen at linux.intel.com>

Not everyone who includes speexdsp_config_types.h will have a test
which defines those, and if we've chosen to use the stdint types at
configure time then we know exactly which header(s) are available, so
just choose the best one then and generate the header to use it.

This patch, including the above text, is copied from a commit in the
speex repository[1]. The original commit for speex was made by Ron
<ron at debian.org>.
