configure.host revision 130561 
1# This file is a shell script that overrides some of the tools and
2# flags used on a host specific basis.

4# Since the "bfd/hosts" directory is shared by the bfd, opcodes, and
5# binutils directories (at least), the index to it is also shared.
6# This is that index.  Each configure.in file should source this file
7# in its per-host part.
8
9# This sets the following shell variables:
10#  HDEFINES		host specific compiler options
11#  host64		set to true if 64 bit types are as fast as 32 bit
12#  HOST_64BIT_TYPE	host 64 bit type
13#  HOST_U_64BIT_TYPE	unsigned 64 bit type (not needed if 64BIT_TYPE is long)
