math.h errors with PowerPC target?

[nirav dot dalal at teradyne dot com]

Hi,

I'm having issues with compiling gcc when math.h is included
with PowerPC target.

I have tried switches to include math.h, like -lm, -ffast-math

but everytime it gives me the following errors:
----------------------------------------------------------------------------
In file included from foo.cpp:3:
c:/mingw/include/math.h:31:20: _mingw.h: No such file or directory
In file included from foo.cpp:3:
c:/mingw/include/math.h:149: error: syntax error before `double'
c:/mingw/include/math.h:150: error: syntax error before `double'
c:/mingw/include/math.h:151: error: syntax error before `double'
c:/mingw/include/math.h:152: error: syntax error before `double'

c:/mingw/include/math.h:158: error: syntax error before `double'
c:/mingw/include/math.h:159: error: syntax error before `double'
..........
---------------------------------------------------------------------------

The gcc compile command used for x86 target is as under:
$ g++ -I "c:\inc" -ansi -mcpu=604 -mstrict-align -ansi -nostdinc -fvolatile
-fno-builtin -fno-for-scope
  -mlongcall -DRW_MULTI_THREAD -D_REENTRANT -DCPU=PPC604 -DPRJ_BUILD -O3
-DINCLUDE_CACHE_L2 -DVXWORKS -DPPC
  -DDSPBYTECODE -D__GG_IDL_CPP_STATIC__ -D__GGI_IDL_CPP_STATIC__
-fno-exceptions -c -UWIN32 -ffast-math
  foo.cpp

Any help on this problem is appreicated.

Thanks,
