Subject: configure.in: Include <stdint.h> and <inttypes.h> when checking for double storage... 
X-Git-Tag: collectd-4.6.0~157
X-Git-Url: https://git.octo.it/?a=commitdiff_plain;h=dfc4819ad20c8d959d154e4ad3a3701cc7233f63;p=collectd.git

configure.in: Include <stdint.h> and <inttypes.h> when checking for double storage layout.

Some systems, for example Solaris 9, don't have <stdint.h> and define
`uint32_t' via <inttypes.h> instead. Be more permissive by including
both header files when checking how doubles are stored in memory.
