Subject: [PATCH] build: Use AC_HEADER_MAJOR to find device macros
c4e390
c4e390
Depending on the OS/libc, device macros are defined in different
c4e390
headers. This change ensures we include the right one.
c4e390
c4e390
sys/types.h - BSD
c4e390
sys/mkdev.h - Sun
c4e390
sys/sysmacros.h - glibc (Linux)
c4e390
c4e390
glibc currently pulls sys/sysmacros.h into sys/types.h, but this may
c4e390
change in a future release.
