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