bug#11007: incorrect dependency style (depmode) of tcc

[Vincent Lefevre]

I've reported the following bug on the Debian BTS:

  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=663705

for Automake 1.11.3.

When I configure MPFR with CC=tcc, as soon as a .c file is modified or
I do a "make clean", I get errors when I want to rebuild MPFR.

For instance, after a "make clean" and "make":

Making all in doc
make[1]: Entering directory `/home/vlefevre/software/mpfr/doc'
make[1]: Nothing to be done for `all'.
make[1]: Leaving directory `/home/vlefevre/software/mpfr/doc'
Making all in src
make[1]: Entering directory `/home/vlefevre/software/mpfr/src'
/usr/bin/make  all-am
make[2]: Entering directory `/home/vlefevre/software/mpfr/src'
exceptions.c \ :
/home/vlefevre/dash/bin/dash: exceptions.c: Permission denied
make[2]: *** [exceptions.lo] Error 126
make[2]: Leaving directory `/home/vlefevre/software/mpfr/src'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/home/vlefevre/software/mpfr/src'
make: *** [all-recursive] Error 1
zsh: exit 2     =make

The problem appears to be due to the src/.deps/*.Plo files.

In the config.log file:

configure:4362: checking dependency style of tcc
configure:4473: result: icc

Of course, there's no such problem with --disable-dependency-tracking.
