gcc 3.1.1 for cygwin generates __imp_symbol

gcc 3.1.1 for cygwin generates __imp_symbol

[Manik, Raina (IE10)]

Hi all,

	I'm using gcc 3.1.1 on cygwin (i686) and
	i'm doing something to the tune of 

	gcc -c foo.o $(CFLAGS) foo.c

	and all external references in foo.c are prefixed
	with __imp.
      ^^^^^^^^^^^
	i.e nm foo.o shows something like ...

	U	__imp_external_reference 

	for a function external_reference(). It's desirable
	for me to make generate _external_reference() instead
	since i'm having trouble linking this .o file link
	with other libBAR.a files generated using GNU tools.

	The gcc flags i'm using are ...

	-c -fno-exceptions -fno-rtti -march=pentium 
	-falign-functions=64 -Wa,--no-warn  -finline-functions -O3 

	Please let me know if there is a way of supressing gcc
	from generating the __imp prefix for all externally referenced
	symbols. 

	I looked at the gcc documentation and came it came up with nothing
	on this. Am i missing something or is it just my gray cells fizzing
	out ?

	Appreciate any help/pointers/[M's in RTFM's] on this ;)

All,

I discovered the reason for this. It's because of
__atribute__ ((dllimport)) in the function definition.

Hence this has nothing to do with GCC for cygwin and
it was something in my code which was doing this ...

Before someone wakes up to flame me, for lameness (i'm
definitely not giving anyone ideas :) let me retract my
email. 

Thanks for your time,
Best of luck,
Manik Raina
