xl C/C++ compiler to GCC compiler

Hi,
we are converting from IBM-AIX(xl c/c++ compiler) to Linux(GCC complier).
As a part of this i need to change the CFLAGS.
The xl c/c++ complier CFLAGS is

CFLAGS := $(CDEBUG) $(PROJECT_INCLUDE_DIRS) $(COBJECT_MODE) -qcpluscmt -qmakedep -qcheck=all \
-qalign=bit_packed $(LINT_FLAGS) -D_LARGE_FILES -qchars=signed \
-qsuppress=1506-191:1506-495:1506-374:1506-451:1506-416

Please let em know the equivalent flags in GCC version.

Thanks in advance,
Pravin.

MKDEP(1)						    BSD General Commands Manual 						  MKDEP(1)

NAME
mkdep -- construct Makefile dependency list SYNOPSIS
mkdep [-ap] [-f file] [flags] file ... DESCRIPTION
mkdep takes a set of flags for the C compiler and a list of C source files as arguments and constructs a set of include file dependencies which are written into the file ``.depend''. An example of its use in a Makefile might be: CFLAGS= -O -I../include SRCS= file1.c file2.c depend: mkdep ${CFLAGS} ${SRCS} where the macro SRCS is the list of C source files and the macro CFLAGS is the list of flags for the C compiler. The options are as follows: -a Append to the output file, so that multiple mkdep's may be run from a single Makefile. -f Write the include file dependencies to file, instead of the default ``.depend''. -p Cause mkdep to produce dependencies of the form: program: program.c so that subsequent makes will produce program directly from its C module rather than using an intermediate .o module. This is useful for programs whose source is contained in a single module. SEE ALSO
cc(1), cpp(1), make(1) FILES
.depend File containing list of dependencies. HISTORY
The mkdep command appeared in 4.3BSD-Tahoe. 4.2 Berkeley Distribution June 6, 1993 4.2 Berkeley Distribution
