# Makefile fragment for AmigaOS host

# Each compilation environment (Manx, Dice, GCC, SAS/C, etc) provides its
# own equivalent of the UNIX /usr/include tree.  For gcc, the standard headers
# are in /gg/include and system specific headers are in /gg/os-include.
# Use these paths for fixincludes.

SYSTEM_HEADER_DIR = $(prefix)/include

# Uncomment the following macro to get a resident GCC. We don't do it
# by default, since we want to support users with mc68000.
# WARNING!  If you uncomment this, you MUST add the same flags to the
# libiberty's Makefile (libiberty is now linked into GCC executables).

#RESIDENT = -m68020 -resident32

# Additional host flags that are not used when compiling with GCC_FOR_TARGET,
# such as when compiling the libgcc* runtime archives. GCC uses stack
# a lot, and since AmigaOS provides processes with a small, fixed size
# stack, we have to generate code that will extend it whenever necessary.

XCFLAGS = -mstackextend $(RESIDENT)

# AmigaOS supports "AmigaGuide(R)" hypertext files. For GCC, these are
# build with a custom "makeinfo".

# Arrange for guides to be build with GCC, in the build directory.
