Subject: configure: request/set the compiler in C99 mode
X-Git-Tag: android-x86-4.4-r3~53
X-Git-Url: http://git.osdn.net/view?p=android-x86%2Fexternal-libdrm.git;a=commitdiff_plain;h=e59f00fb43c2b83bdadb17fa35c3018f817a3806

configure: request/set the compiler in C99 mode

Required by intel and drmstat at least. Considering that every compiler
used to build libdrm is C99 compatible, just enable it for the whole
build.
