Thread model: simple and C

[Marcos Dione <Marcos_David dot Dione at sophia dot inria dot fr>]

    first of all: I'm not subscribed to gcc's ML, so please cc: in any answers.

    I'm cross-compiling an application to a platform whose SDK brings a gcc 
which reports 'Thread model: single'. even so, the platform implements a 
rudimentary thread support (a subset of posix), which leads me to think 
that it should be possible to use it in C programs.

    why? because the only reference to Thread model I could find in gcc's 
doc is in libstdc++'s manual[1] and no other useful reference about simple 
thread model.

    in particular, my main concern is not about our own program but a library 
we use, namely, Boehm's GC, which I see is included in gcc's code. I already 
asked Boehm itself (via the GC's ML[2]) but he's not sure what are the 
implications.

    so, in short: does a simple Thread model have any impact on C-only 
programs that could use threads? in particular, how it does impact 
Boehm's GC usage in a C-only program? if the impact is negative, would 
you say that the original gcc is compiled with the wrong flags, given that 
there is a bit of pthreads implementation in the platform?
