Re: changing the default compilers for autoconf

[Sanjay Gianchandani]

Hi,
I am aware of that method, but that method requires this to be done for each
application when it is being built...
I am looking for a solution which doesnt make any changes to how the user
uses autoconf, so that it is not required
for each application...
moreover this is just for C/C++ compilers, which will definitely work in a
majority of application, but apart from this
Sun Studio provides a much more efficient(on solaris) fortran compiler and
also sun performance libraries...
therefore i am looking for a way to modify autoconf itself so that when it
is run on Solaris, it would be default
look for the Sun studio compilers and libraries, not the gnu ones..

so in effect such a thing can just be added into autoconf so that it wud run
as it runs on any other system right now,
 but when it is run on solaris machines it would work in a different manner(
i.e. go for sun studio stuff instead of gnu
stuff)

thanks~!
