export PATH=/some/path:/some/other/path:/and/another/path:.....
The PATH variable is a list of directory names separated by colons. The list of directories is searched in the order in which they appear in this list. Find out where gcc 3.3 is and add this directory to the beginning of the current value of $PATH:
PATH=/some/new/directory:$PATH
Display the $PATH variable to make sure everything was done correctly:
echo $PATH
You might get a list which reads like:
/some/new/directory:/bin:/etc:/usr/bin:/usr/bin/X11:/usr/ucb:....
or something such. This should do it. Probably you have to change the library paths and other parts of the environment too when you change the compiler version.
I hope this helps.

dummy_cs
DUMMY_CS(4) Kernel Interfaces Manual DUMMY_CS(4)
NAME
dummy_cs - PCMCIA dummy device driver
SYNOPSIS
insmod dummy_cs.o [pc_debug=n] [free_ports=n] [irq_list=i,j,...]
DESCRIPTION
The dummy_cs module has two purposes. It is intended as a demonstration of how to write the PCMCIA interface code for a client driver, and
the source code is heavily commented. It is also written to function as a sort of generic ``point enabler'': when bound to any PCMCIA IO
card, it will read the card's Configuration Information Structure, and configure the card appropriately. The configuration includes set-
ting up IO and memory windows, configuring the card for interrupts, and initializing the card's PCMCIA configuration registers.
It turns out that many cards report incomplete or inaccurate configuration information, due to vendor carelessness and the complexity of
the data format. A vendor driver can generally take for granted many configuration details, so there is not much incentive for vendors to
ensure that the on-card information is complete. Thus, the dummy_cs module is limited by its generality: since it makes no assumptions
about card types, it is forced to rely on the card information, for better or worse.
PARAMETERS
pc_debug=n
Selects the PCMCIA debugging level. This parameter is only available if the module is compiled with debugging enabled. A non-zero
value enables debugging.
free_ports=n
A flag indicating if the IO ports allocated for the card should be freed from the kernel resource maps. This is useful if the dummy
driver is being used to configure a card in preparation for loading a specific PCMCIA-unaware driver. The default is 0 (false).
irq_list=i,j,...
Specifies the set of interrupts that may be allocated by this driver.
