**************************************************************************
*** The GCC compiler is being used but the option "--enable-gcc-opts"  ***
*** was not specified to the configure script.  The Gambit-C system    ***
*** will compile correctly but the code generated by the GCC compiler  ***
*** will be suboptimal and the executables will run slightly slower    ***
*** than if "--enable-gcc-opts" is specified.  On the other hand the   ***
*** build process will be faster and require less memory.  If you have ***
*** lots of RAM memory (>= 2 Gbytes) and you are willing to wait for   ***
*** the longer build try the configure option "--enable-gcc-opts".     ***
